The Detroit Lions could be without backup quarterback Tim Boyle for an extended period after he injured the thumb on his throwing hand on the opening drive of Friday's 27-17 preseason loss to the Indianapolis Colts.
Boyle appeared to hit his right hand on the helmet or shoulder pad of Colts defensive end Kemoko Turay as he lost the ball after being hit from behind by Kwity Paye.
He stayed in for the next series and led the Lions on a 14-play, 75-yard touchdown drive, then gave way to David Blough for the rest of the game.
