Two days after linebacker E.J. Henderson was put on injured reserve with a foot injury that will cause him to miss the rest of the season, little brother Erin Henderson missed practice Wednesday with a concussion.

Erin Henderson was injured on Monday night against the Saints while covering a punt. He was leveled by a blind-side hit from Jo-Lonn Dunbar that helped spring Reggie Bush for his first touchdown of the game.

Henderson's availability for this week's game against Detroit is still in question.

Receiver Bernard Berrian was limited in practice with a knee injury, but is expected to play against the Lions on Sunday.
