The San Francisco 49ers begin the second half of their 2017 regular season with a home game against the Arizona Cardinals in Week 9. You know the drill, follow along here for news, updates and highlights as the 49ers look for their first win of the year.

PREGAME

We knew six of the 49ers seven inactives before gameday. San Francisco's injury-plagued roster has a few players stepping into new or increased roles.

Here's who won't play for the 49ers: Joe Staley, Solomon Thomas, Pita Taumoepenu, K'Waun Williams, Garry Gilliam, D.J. Jones and Aaron Lynch.

Trent Brown might start at left tackle in place of Staley, which would mean Darrell Williams Jr. woud likely step in at right tackle. Aldrick Robinson will start in place of Pierre Garçon (neck), who was placed on Injured Reserve, and be an every-down player for the 49ers offense. Erid Reid is going to move back to strong safety while Jaquiski Tartt starts at free safety in place of Jimmie Ward (forearm), who was also placed on IR.

Here are the Cardinals inactives: Xavier Williams, Ricky Seals-Jones, Will Holden, Daniel Munyer, Scooby Wright III, D.J. Foster and Chad Williams.

The 49ers got moving quickly with a 6-yard run by Pierre Garçon and a 14-yard pass from C.J. Beathard to George Kittle. Kittle hobbled off after the play. Kyle Juszczyk then caught a short pass and fumbled. Patrick Peterson picked up the loose ball and returned it all the way to San Francisco's 6-yard line.

Two carries from Peterson went just three yards to set up 3rd-and-goal from the 49ers 3-yard line.

After scrambling to his right, Stanton found Jaron Brown for a 3-yard touchdown to make it 7-0, Cardinals. (10:15)

--

Hyde gained one yard on first down, and Beathard's next two passes fell incomplete. The 49ers punted following the three-and-out.

--

Arizona set up at their own 37-yard line. A first-down pass to Fitzgerald lost a yard. Peterson lost two yards on second down. John Brown dropped a third-down throw that would have moved the chains, and Arizona punted it back to San Francisco.

--

A few injury updates to the tight ends. Cole Hikutini is out with a knee injury. Kittle returned after leaving the game briefly with a leg injury. Hyde gained 13 yards to open the drive. The running back then caught a pass for an 18-yard gain to Arizona's 48-yard line. The drive stalled when Beathard was sacked on third down.

--

Arizona went three-and-out again. Tartt made a nice stop to end the drive when Andre Ellington looked to have a clear route for a first down.

--

The 49ers went three-and-out as well as the Cardinals got another third-down sack of Beathard.

Arizona continued the string of three-and-outs.

--

Beathard, who missed Goodwin on a deep ball on the 49ers last possession, connected with San Francisco's fastest wideout for a 52-yard gain down the middle of the field. Goodwin did well to adjust to the football and secure the catch. A holding penalty cost the 49ers 10 yards. Trent Taylor caught a 10-yard pass on 3rd-and-17 to bring on the field-goal unit.

SECOND QUARTER

On 2nd-and-10 from the 15-yard line, Reid intercepted Stanton in the end zone. Reid took the ball away from Gresham, who was the intended receiver up the right seam. The turnover gave San Francisco the ball at the 20-yard line.

--

A 9-yard pass to Kittle gave the 49ers a much-needed first down as the game reached the two-minute warning. Passes of four yards to Kittle, seven yards to Hyde, seven yards to Robinson and 12 yards to Taylor helped San Francisco reach Arizona's 38-yard line. A false start penalty halted the progress and moved the 49ers back to the 43-yard line.

The drive stalled from there. Penalties continue to be drive killers for the 49ers offense. Pinion's punt was a beauty, downed at Arizona's 6-yard line.

Arizona took a knee as the team's went in for halftime. San Francisco is still looking for its first touchdown of the season against Arizona.

THIRD QUARTER

San Francisco got the ball first to open the second half. Tartt, Taylor and Elijah Lee are all out for the 49ers as the team's injury count continues to rise to a ridiculous number. Kendrick Bourne hauled in a 25-yard pass for his first-career reception. Hyde and Juszczyk combined for another first down.

On 1st-and-goal, Beathard scrambled to the right and dove for the pylon. The play was initially called a touchdown but was then overturned upon review. Beathard stepped out at the "1.5-yard line" according to the officials. Hyde was stuffed on 2nd-and-goal. On the play, Juszczyk went down with an injury before walking off slowly.

Beathard got into the end zone on third down with a 1-yard touchdown run on a read option to make it 14-10, Cardinals. (9:43)

Arizona began marching immediately. Fitzgerald caught a 14-yard pass on third down. The officials then threw a very late flag for illegal contact on an incomplete pass that would have ended the drive. San Francisco still got off the field.
