DENVER -- The Houston Texans (1-1) and Denver Broncos (2-0) face each other in their third preseason game Saturday night at Sports Authority Field at Mile High Stadium. Here's what to watch for:

1. Quarterback Ryan Fitzpatrick: He recovered in a big way from his uninspiring debut this preseason. Two scoring drives showed a marked improvement last weekend compared to his performance in the Texans' preseason opener against the Arizona Cardinals. The Fitzpatrick who appeared against the Falcons is much closer to the quarterback I've seen in practices lately than the one who could barely stay on the field in Arizona. His improvement needs to be a trend, though. Fitzpatrick needs to be more consistent, especially outside of two-minute drills.

2. The slot receivers: The position is a competitive these days. Mike Thomas was the early leader, and he has still looked excellent in practices, but don't count out Keshawn Martin. This week's game will be important for both. Thomas sat out last weekend against Atlanta after getting knocked in his helmet during the week of practices against the Falcons. Martin and undrafted rookie Travis Labhart really took advantage of his absence.

3. The secondary: The Texans' depth at defensive back grew before our eyes from Week 1 to Week 2. I don't expect starting cornerback Johnathan Joseph to play tonight, which means another serious look at those guys against the best passing game in the NFL. We'll couch this by saying preseason games involve a pared down playbook and little game-planning. But the Texans will still learn a lot by watching cornerbacks such as A.J. Bouye, Elbert Mack and Andre Hal, who have all had promising moments this preseason. Mack, especially, had a strong week against the Broncos in practice. He could fight his way onto the roster in the next two weeks.
