Apparently, the 49ers didn’t dodge every injury bullet during their six-day trip to Maryland. The team on Wednesday placed linebacker and special teams standout Blake Costanzo on injured reserve and signed another inside linebacker with special teams ability, Kion Wilson. Costanzo was injured in Thursday’s game but did not leave the contest. The team did not specify his injury.
Wilson (6-1, 239) joined the Chargers as an undrafted free agent in 2010. He’s played in 15 games (two starts) since with nine tackles on defense and 11 on special teams. He played for both the Chargers and Panthers in 2011 and with the Steelers last season where he had nine tackles in seven games (two starts). Wilson is familiar to inside linebackers coach Jim Leavitt having played for him at South Florida.
A number of the 49ers’ special teams leaders, including Costanzo, 30, Ray Ventrone, 31, and Kassim Osgood, 34, are in their 30’s. Wilson is 27.
Costanzo was the charismatic captain of the 49ers’ swagger-laden coverage units in 2011, which was nicknamed “The Tony Montana Squad.” He was signed by the Bears in free agency in 2012. The 49ers reacquired him in June. He joins running back Kendall Hunter and receiver Chuck Jacobs on injured reserve.
