The San Francisco 49ers are back home for a Week 6 matchup against the Baltimore Ravens as they look to end their current three-game losing streak. Both teams enter the contest with a 1-4 record, desperate for a win to keep pace in their respective divisions.

Here we go. Pregame/Injury Notes

Reggie Bush (calf) will miss his third game of the season. The running back was listed as doubtful going in so the news isn't a major suprise. The big question is who will assume backup running back duties behind Pierre Garçon, who is active despite his foot injury. It will be either Jarryd Hayne or 2015 fourth-round pick Mike Davis.

Vernon Davis (knee) is active after missing the last two games after being listed as questionable.

For the Ravens, Steve Smith Sr. (back) has returned to the lineup after missing his team's Week 5 contest against the Cleveland Browns. Smith tweeted an image reading "guess who's back?" this morning. He automatically becomes Joe Flacco's top target and the 49ers should expect to see Smith get 10-15 targets.

Baltimore's starting running back Justin Forsett (ankle) and star pass-rusher Elvis Dumervil (groin) are also active and will provide a boost for the Ravens.

Full list of 49ers inactives: WR Bruce Ellington, RB Reggie Bush, LB Gerald Hodges, G Brandon Thomas, OL Ian Silberman, NT Mike Purcell and LB Corey Lemonier.

Full list of Ravens inactives:WR Darren Walker, WR Breshad Perriman, CB Ladarius Webb, S Terrence Brooks, RB Raheem Mostert, C Ryan Jensen and DL Chris Canty.

First Quarter

The 49ers got the ball to start the game, but after three-straight first downs, the drive stalled on the Ravens 37-yard line. Anquan Boldin's two catches for 21 yards highlighted the possession.

On San Francisco's second drive, Bruce Miller delivered the early highlight of the game. On a quick out, Miller took a short pass from Colin Kaepernick up the right sideline for 28 yards. On the play, the fullback unleashed a stiff arm to throw a Ravens defender off of him as he added an extra 10 yards to the play.

Miller's catch and run led to a 53-yard field goal from Phil Dawson to put the 49ers on the board first, 3-0. (7:05)

After a second consecutive stop for the 49ers defense, it was Miller time again.

The fullback started the drive with a nine-yard catch. Two plays later, on 3rd-and-1, Miller ran a wheel route up the right sideline. Kaepernick hit the wide-open Miller, who made the reception and took it 52-yards. The fullback's big first quarter resulted in three receptions for 89 yards. Entering the week, Miller had just three catches for 30 yards on the season.

A 31-yard Dawson field goal made it 6-0 49ers. (2:00)

Second Quarter

The Ravens got on the board early in the second quarter. Two 19-yard passes to Smith and Crockett Gillmore got Baltimore into the red zone.

San Francisco's defense held, and forced the Ravens to settle for a 22-yard Justin Tucker field goal to cut the lead to 6-3. (13:16)

It took the 49ers just two plays to answer the Ravens score. After a Carlos Hyde 4-yard run on first down, Torrey Smith torched former San Francisco cornerback Shareece Wright up the right sideline on a double move. Kaepernick hit Smith in stride, and the receiver took off for the 76-yard touchdown reception. The play showcased Smith's top-level speed as nobody in the Ravens secondary could catch up. It also marked Smith's longest reception of his career, topping his 75-yard touchdown earlier this season against the Pittsburgh Steelers.

Smith's touchdown gave San Francisco a 13-3 lead. (12:27)

A Michael Wilhoite interception of Flacco on the following drive put the 49ers offense back in business. A combination of rushes from Kaepernick and Hyde got the 49ers* *to the Baltimore 8-yard line before the drive stalled.

Dawson's third field goal of the day, this time from 26 yards, extended San Francisco's lead to 16-3. (8:04)

The 49ers defense stood tall once again on the Ravens next possession. Flacco was able to pick up a few chunk plays on a 29-yard pass to Smith, followed by a 21-yard run by Forsett. A Javorius Allen run for no gain and two incompletions led to another Ravens field goal. On one of the incompletions Aaron Lynch chased Allen, a running back, up the right sideline and kept tight coverage.

Tucker's 36-yard field goal made it 16-6 49ers. (4:19)

Halftime

The 49ers took a 16-6 lead into the halftime break. The Ravens will get the ball to start the third quarter.

Here are some notable stats:

• San Francisco held Baltimore's offense to just 1-of-7 on third-down attempts.

• The 49ers out-gained the Ravens 279 yards to 147 yards.

• San Francisco is winning the turnover battle 1-0.

Third Quarter

Kenneth Acker began the second half with his second career interception. On a first-down play from the 49ers 41-yard line, Flacco threw the ball up for grabs with no Ravens receiver in sight. Acker made the easy catch for the interception. More impressively, Acker returned the pick 45 yards to the Ravens 38-yard line.

Acker's pick was the 49ers second interception of the game, marking the team's first contest with multiple takeaways this season.

A 26-yard catch and run from Anquan Boldin set up the 49ers next scoring opportunity. On the third-down conversion, Boldin caught the pass up the right seam and broke multiple tackles before finally being taken down.

Dawson's 42-yard field goal, his fourth of the day, gave the 49ers a 19-6 lead. (7:39)

Steve Smith followed up Boldin's play with an impressive play of his own. With the Ravens marching down the field, it was Smith who exploded for Baltimore's biggest play of the game. Flacco, under pressure, heaved a pass off of his back foot towards the left corner of the end zone to find a diving Smith for a 39-yard score.

Smith's touchdown brought the Ravens within one score, 19-13. (2:29)

Fourth Quarter

Baltimore had the first scoring opportunity of the final period. On a 3rd-and-4 play from the 49ers 27-yard line, Tramaine Brock kept up step for step with Kamar Aiken in the end zone and forced an incomplete pass. Tucker chunked the ensuing field-goal attempt from 45-yards to keep the teams separated by six points.

Two plays later, Kaepernick delivered what was quite possibly his best throw of the season. Rolling left on second down, Kaepernick threw across his body deep down field for a 51-yard completion to Boldin. Baltimore challenged the ruling on the field of a catch but the play stood as called. Unfortunately for the 49ers, Boldin was injured on the play and did not return to the game.

Kaepernick followed that throw up with his second touchdown of the game. Scrambling in the pocket and keeping the play alive, Kaepernick found Patton in the end zone from 21-yards out. Patton lost

his man in coverage and was able to secure his first career touchdown.

Patton's 21-yard score added to the 49ers lead, putting San Francisco up 25-13 after a failed two-point conversion attempt. (10:52)

Baltimore wouldn't go away.* *Facing 4th-and-goal from the 49ers 2-yard line, the Ravens needed a touchdown to keep the game alive. Flacco rolled to his right and found Kamar Aiken for the 2-yard touchdown. Aiken, very similarly to Patton's touchdown, was well covered but found a way to break free as Flacco kept the play alive.

The Ravens second touchdown of the game pulled them within one score, 25-20.

After forcing the 49ers to punt, Baltimore got the ball back with 1:06 remaining and no timeouts. With :06 remaining from the 49ers 35-yard line, Flacco threw up a Hail Mary intended for Steve Smith. Reid batted the play down to secure the 49ers win.

San Francisco held on for the 25-20 victory, ending a four-game losing streak and improving to 2-4 on the season.
