49ers second-year offensive lineman Nick Zakelj has been placed on Injured Reserve and is out for the season.
Zakelj suffered a torn biceps during his brief appearance against the Jaguars in Week 10. He’s eligible to return, but his injury required surgery and is season-ending according to head coach Kyle Shanahan.
The injury to the reserve OL makes San Francisco a little thinner on the interior, and it comes at the same time starting right tackle Colton McKivitz is working through a knee issue.
Shanahan also said the club will bring an offensive lineman up from the practice squad. Undrafted rookies Ilm Manning and Corey Luciano, as well as veteran Jesse Davis are the three OL available in-house.
Zakelj could still figure into the team’s long-term plans at guard as he transitions from his natural tackle spot.
San Francisco hasn’t made a corresponding move yet. Their open roster spot could go to one of the practice squad OL, but it might also go to one of the players on an injured list who has an open practice window. Samuel Womack, Robert Beal and Darrell Luter Jr. are all eligible to be activated after their practice windows opened last Monday.
