San Francisco 49ers

Report: Rookie Marcus Martin to miss eight weeks

SANTA CLARA -- Rookie center Marcus Martin suffered an injury to his kneecap late in Sunday’s game and will miss eight weeks, according to a report by The San Francisco Chronicle.

Martin, a third-round draft pick in May, was the top backup at center and even received a few snaps with the first-team offensive line against the Chargers. Several others, including Ryan Seymour, Adam Snyder and rookie Dillon Farrell, also have experience at center. Farrell filled in after Martin was carted off the field Sunday.

The 49ers must sit eight players each week, and it’s conceivable that they don’t make any moves with Martin. They also could place him on injured reserve, which will end his season, or on injured reserve with a designation to return. The latter would allow him to come back in the second half of the season.

Veteran nose tackle Glenn Dorsey, however, also is a candidate for IR with a designation to return after suffering a biceps tear Aug. 1. Teams only can choose one player for that designation and must assign it on Sept. 2.

After the game, Martin took to Twitter. “What don’t kill me, will only make me stronger I’ll be back better than ever before, thank you everyone for the well wishes!! Love y’all!” he wrote.
