Three things to watch for Thursday night in the Arizona Cardinals' fifth and final exhibition game, this one at home against Denver (11 p.m. ET):
1. Lindley's opportunity. Rookie quarterback Ryan Lindley, a sixth-round choice from San Diego State, makes his first professional start. The Cardinals aren't considering him as a Week 1 starter, but this game could help them decide how early Lindley might be ready. The Cardinals think he has long-term starting potential. But with concerns at offensive tackle, will Lindley have time to operate?
2. Pass protection. Left tackle D'Anthony Batiste and right tackle Bobby Massie will start this game. They provided Arizona with its best combination against Tennessee last week. The Broncos should test them for as long as Elvis Dumervil and Von Miller are in the game, and probably for longer. Can the Cardinals emerge from this game feeling better about their ability to protect the quarterback?
3. Floyd watch. First-round draft choice Michael Floyd should get ample playing time to improve upon his modest preseason totals (three catches covering 18 yards). Kevin Kolb and John Skelton are expected to sit out, however, so Floyd won't get a chance to work on in-game chemistry with the Cardinals' as-yet-unnamed starter for the regular season.
