ALLEN PARK, Mich. -- Reggie Bush missed his second straight day of practice for the Detroit Lions on Thursday with an injured calf.

Bush was at practice, however, working on the side holding a ball high in his right arm while one of the Lions' staffers poked it with a giant jousting stick.

Defensive end Israel Idonije and practice squad wide receiver Patrick Edwards were the only two other players not practicing Thursday, although both were in attendance off on the side.

Both wide receiver Calvin Johnson and safety Louis Delmas returned to practice.
