The 49ers made a flurry of roster moves on Saturday to bring up four players from the practice squad to be eligible to play in Week 14 against Washington.
The 49ers placed veteran offensive lineman Tom Compton on injured reserve after he sustained his second concussion in three weeks. Players who go on IR must spend at least three games on the list. The 49ers only have four games remaining in the regular season.
The 49ers were also granted a roster exemption for defensive lineman Kevin Givens, who left the club's base in Arizona this week for the birth of his daughter on Thursday.
In addition to Givens, the 49ers do not expect to have starting nose tackle D.J. Jones, who did not practice this week due to an ankle sprain.
The 49ers promoted defensive lineman Alex Barrett to the active roster and elevated undrafted rookie defensive lineman Darrion Daniels from the practice squad.
Barrett has appeared in four games for the 49ers this season. He has registered three tackles. Daniels was called up for the Week 12 game against the Rams and played 15 snaps.
Offensive lineman Dakoda Shepley is set to make his debut with the 49ers. He was added to the practice squad after the team's cuts at the end of training camp.
Briean Boddy-Calhoun also was promoted to the active roster after being signed Wednesday to the team's practice squad.
Emmanuel Moseley (hamstring) is doubtful and K'Waun Williams (ankle) is questionable. Dontae Johnson is in line for his second start at nickel back, and Boddy-Calhoun would serve as a backup.
Boddy-Calhoun (5-foot-9, 193 pounds) is a five-year veteran who has appeared in 46 career games with 22 starts. He played 43 games from 2016 to ’18 with the Cleveland Browns. Last year, he saw action in a combined three games with Indianapolis and Houston.
