Hasselbeck -- at 40, the oldest non-kicker in the NFL -- is battling a bacterial infection, and he isn't sure if he can play a full four quarters, he told NFL Network's Stacey Dales. Hasselbeck said he felt drained after practice Wednesday and that he spent all Thursday afternoon receiving IV fluids. He's concerned about what his energy levels will be like against the Texans, he told Dales.
