49ers lose C Kilgore for season with ankle injury
San Francisco 49ers center Daniel Kilgore is scheduled to undergo season-ending surgery Tuesday on a fractured left ankle sustained in the third quarter of Sunday night’s loss at Denver.
Head coach Jim Harbaugh said Monday the injury is similar to what nose tackle Ian Williams suffered in Week 2 of the 2013 season at Seattle that required four operations and kept him sidelined until training camp this year. Kilgore, who will be placed on injured reserve, was carted off after getting hurt when linebacker Brandon Marshall inadvertently ran into his lower leg at the end of a run by Frank Gore during a 42-17 loss to the Broncos.
Marcus Martin, a 20-year-old rookie third-round draft pick, is the favorite to fill in for Kilgore on the starting offensive line. Martin recently returned to practice following a training camp knee injury.
Martin’s NFL debut would likely be Nov. 2 at home against the Rams following the Niners’ bye week.
Replacing Kilgore is a big task. But while Martin hasn’t played this season, he has ample experience at the position.
The 70th overall pick out of Southern California, he played 38 games — with 33 starts — over three seasons with the Trojans. Martin started all 13 games at center last year while helping USC rush for 2,419 yards and 29 touchdowns, and earning First-Team All-Pac-12 honors.
