SANTA CLARA, Calif. - The 49ers are adding depth to the interior of their offensive line in a trade with the Ravens.
San Francisco is acquiring reserve center Nick Easton from Baltimore, who announced the trade on Twitter, a day after the 49ers waived former fourth-round pick Joe Looney Friday in their first wave of final roster cuts.
Last year's starting center Daniel Kilgore this week was placed on the reserve/physically unable to perform list after undergoing a second surgery on his fractured lower leg sustained midway through last season. He will be out at least the first six weeks of the new year. With Kilgore's absence and Looney's release, the 49ers were were lacking depth at the position.
The 49ers will likely start second-year player Marcus Martin at center, who started the first two preseason games at right guard. He replaced Looney, with rookie sixth-round pick Ian Silberman and second-year player Brandon Thomas also getting time with the first team.
However, head coach Jim Tomsula announced this week Jordan Devey, acquired Aug. 18 in a trade with the Patriots, will be the team's starter at right guard. Dillon Farrell, who appared in eight games a reserve last year, was waived Saturday, according to a report from the Sacramento Bee.
Easton (6'3", 300) played 155 snaps for the Ravens this preseason, where he didn't allow a sack or quarterback hit, according to Pro Football Focus. The Harvard alum excelled in run blocking, which likely enticed the 49ers, who want to re-establish their running game after relying more on Colin Kaepernick's arm in 2014.
Easton joined the Ravens as an undrafted free agent this spring. San Francisco is sending Baltimore an undisclosed draft pick.
