49ers Vs. Giants 2012: Offensive Line Injuries Hurting Both Teams

Read More: David Baas (C - NYG), Adam Snyder (G - ARI), Chilo Rachal (G - CHI), Mike Iupati (G - SFX), New York Giants

The San Francisco 49ers may have to beat the New York Giants without starting guard Mike Iupati, who exited the game and headed to the locker room late in the first quarter. The team hasn't officially characterized the injury. Iupati appears to have some sort of leg injury as trainers attended to him as he tried to walk around on the sidelines.

The 49ers shook up their offensive line due to Iupati's absence with Chilo Rachal at right guard and Adam Snyder at left guard. [Update: Iupati has since returned to the game.]

Also getting dinged up was Giants center David Baas. It's unclear what happened to him but he exited the game early in the second quarter and was replaced by Kevin Boothe. Baas missed five games earlier this season so the Giants have some familiarity playing without him.
