The 49ers have now placed two centers on IR this season after moving Marcus Martin to the season-ending injured list. He joins Daniel Kilgore and several other San Francisco starters there.
San Francisco filled Martin’s roster spot by promoting running back Raheem Mostert from its practice squad.
Martin became a key member of the 49ers’ front in both the 2014 and ’15 seasons after subbing in for Kilgore following the starter’s severe leg injury. The former third-round draft choice received more than a season’s worth of starts during Kilgore’s recovery, but after the first-stringer returned last December, Martin hasn’t factored in as much this season. However, Kilgore’s return trip to IR earlier this month opened the door for two more Martin starts.
The 49ers previously ruled out Martin for their Week 17 game against the Seahawks with an ankle injury. The 2-13 team now has 19 players on its IR list, including Carlos Hyde, whose MCL injury forced the team to reshuffle its backfield. Mostert caught on with the 49ers’ practice squad in late November; the second-year UDFA played in two games earlier this season for the Bears.
