The Facts: Foster came up limping on pass play last night, never returned to practice and ESPN.com's Tania Ganguli reports Foster hurt his groin.

Diehards Line: We'll obviously be watching this one closely as Foster has battled a variety of injuries throughout the course of his career -- including a hamstring issue that knocked him out of the team's season finale last year and another groin injury he dealt with last November. Despite the injury issues, Foster finished 2014 with 1,246 yards and eight touchdowns on 255 rushing attempts. He also caught 37 passes for 317 yards and four touchdowns. Stay tuned.
