By TOMMY REZACSt. Joseph PostChiefs head coach Andy Reid confirmed that quarterback Patrick Mahomes, receiver Sammy Watkins and running back Clyde Edwards-Helaire all practiced in at least limited capacity Wednesday as the Chiefs prepare to host the Buffalo Bills in the AFC Championship Sunday.Reid says Mahomes is still in concussion protocol, and is progressing well.“He's looked good, but he's in protocol, so there's only certain things he can do," Reid said. "Today was limited practice, so it fit right in with what he can do. He took all of the snaps. He feels good. We're just going to follow the protocol as close as we possibly can."The only Chief who didn’t practice Wednesday is linebacker Willie Gay (ankle). Bashaud Breeland (corner), who’s also in concussion protocol and Rashad Fenton (corner) both practiced Wednesday.Reid said Thursday is the "bigger, heavier" practice, but thought everyone "progressed well" on Wednesday.If Mahomes cannot go Sunday, backup quarterback and 13-year veteran Chad Henne reaffirms that he’s ready to go if he needs to step in again.“My preparation is going to stay the same," Henne said. "I prepare each and every week as if I'm going to be the starter no matter what happens. I have to be prepared, even if something were to happen and whatever does happen happens. For me, I take it each day at a time. We'll be excited to play."Henne completed 6-of-8 passes for 66 yards and an interception in Sunday’s win over the Cleveland Browns. He also completed 23-of-32 passes for 218 yards and two passing touchdowns in the Week 17 start against the L.A.
