Hasselbeck suffered a jaw injury during Sunday's game against the Texans, according to Zak Keefer of the Indianapolis Star.

EDGE Analysis

Hasselbeck came into the game with back and rib injuries, and while he left briefly with what was believed to be a head injury, he was allowed to return to the game. Charlie Whitehurst came on briefly for Hasselbeck (the third straight game he's done so) and given all the injury issues, it's certainly possible the Colts could turn to Whitehurst in Week 16 against the Dolphins if Andrew Luck (abdomen/kidney) is still not ready to return.
