Recent 49ers acquisition Spencer Long opted to retire, and the team added another depth piece to fill the void. Former Bears starting center Hroniss Grasu agreed to terms with the 49ers, Ian Rapoport of NFL.com tweets.
San Francisco moved on from two-year guard starter Mike Person, who subsequently retired, and center starter Weston Richburg resides on the team’s active/PUP list. Utility man Ben Garland is also battling an ankle injury. The team is also thin at guard, beyond starters Laken Tomlinson and Tom Compton.
Grasu, 29, spent the past two seasons with the Ravens. Injuries sidetracked his run with the Bears. He landed in Baltimore in 2018 but also spent time with Tennessee during that stretch. The former third-round pick started a game for the Ravens in 2018 but has only appeared in four contests over the past two seasons.
