The San Francisco 49ers placed center Daniel Kilgore on injured reserve and promoted offensive lineman Alex Balducci to the active roster from the team’s practice squad, the team announced on Tuesday.
San Francisco has also signed offensive lineman Mitchell Van Dyk to the team’s practice squad.
Kilgore sustained a leg injury in the first quarter against the Jets and was immediately ruled out for a return Sunday for the 49ers’ shorthanded offensive line.
He was injured on a play in which quarterback Colin Kaepernick completed a 6-yard pass to Quinton Patton. Kilgore remained on the ground, grabbing behind his right leg.
After walking off the field slowly, but under his own power, Kilgore remained on the sideline despite being ruled out for a return later in the game.
Balducci (6-4, 310) originally signed with San Francisco on May 6, 2016 as an undrafted free agent from the University of Oregon. After spending training camp with the team, he was waived on September 3 and signed to the team’s practice squad the following day.
Balducci will wear number 75.
Kilgore (6-3, 308) started in each of the team’s 13 games this season.
Van Dyk (6-7, 299) was originally drafted by the St. Louis Rams in the 7th round (226th overall) of the 2014 NFL Draft. He was waived by the Rams on August 30, 2014, signed with the Pittsburgh Steelers on January 15, 2015, and spent the entire 2015 season on the Injured Reserve List. Following his release from Pittsburgh on February 16, 2016, he signed with the Indianapolis Colts on April 21 and spent training camp with the team before his release on September 3.
A 25-year-old native of Paso Robles, Van Dyk attended Portland State University where he appeared in 37 games (31 starts) from 2009-13. He earned All-Big Sky Conference honors as a senior (First-Team) and junior (Honorable Mention).
