Ebron (knee) was placed on injured reserve Saturday, Brooke Pryor of ESPN.com reports.
Reports at the beginning of the week suggested Ebron would miss multiple games and might need surgery. He's now ineligible for Weeks 12 through 14 and could be out even beyond that. Rookie Pat Freiermuth will get more playing time with Ebron sidelined, while Zach Gentry bumps up to No. 2 on the depth chart at tight end.
