The San Francisco 49ers announced on Tuesday that they have claimed defensive tackle Chris Jones off waivers from the Miami Dolphins. In order to make room on the roster, the team placed defensive lineman Arik Armstead on the Injured Reserve List.

Jones (6-1, 293) was originally drafted in the sixth round (198th overall) of the 2013 NFL Draft by the Houston Texans. Following his release from Houston on Aug. 31, 2013, he spent time with the Tampa Bay Buccaneers and was later acquired off waivers by the New England Patriots on Sept. 11, 2013. In three seasons with New England (2013-15), he appeared in 28 games (23 starts) where he registered 79 tackles and nine sacks. In four postseason contests (two starts) with the Patriots, he had nine tackles, one sack and one fumble recovery. He was released by New England on April 15, 2016 and then signed with the Miami Dolphins on April 18. This season with Miami, he picked up seven tackles in seven games played and was waived on Nov. 7.

A 26-year-old native of Brownsburg, Ind., Jones attended Bowling Green State University, where he appeared in 50 games (43 starts) and registered 157 tackles, 28 sacks, two passes defensed, six forced fumbles and five fumble recoveries. A three-time All-MAC performer (First Team in 2011-12 and Third Team in 2010), Jones was also named the MAC Defensive Player of the Year as a senior in 2012.

Armstead (6-7, 292) appeared in eight games (four starts) this season where he finished with 21 tackles, 2.5 sacks and one forced fumble.
