Daniel Kilgore will miss the rest of the season with a left leg injury.

The San Francisco 49ers will give Marcus Martin a shot at center moving forward.

Martin was a third round pick out of USC.

“He’s excelled at the mental aspects,” Jim Harbaugh said. “Before and after he was injured, I’ve been real impressed with that. Even when he knew he was hurt and would be out multiple weeks, he didn’t ease off in the classroom or with his study. I think that bodes well.

“He’s a bright youngster, and he’s champed at the bit to get on the field. I’m excited about his progress and I look forward to good things.”
