INDIANAPOLIS (AP) The Indianapolis Colts deactivated quarterback Andrew Luck and safety Clayton Geathers for Thursday night's game against Pittsburgh.
Both went into the concussion protocol after Sunday's victory over Tennessee and had not yet been cleared to play. Luck is expected to be replaced by backup Scott Tolzien, whose most recent NFL start came in 2013.
Indy's other inactive players are linebackers Deon King and Curt Maggitt, offensive linemen Le'Raven Clark and Austin Blythe and nose tackle Zach Kerr.
