What happened: Head coach Kevin O'Connell announced that offensive lineman Caleb Tiernan is dealing with an ankle injury and is considered week-to-week. O'Connell indicated he expects Tiernan to be available for the regular season. Quarterback Max Brosmer is scheduled to throw today.

Why it matters: Tiernan avoiding a long-term setback preserves offensive line depth. Brosmer's ability to throw signals progress in his own ongoing preseason evaluation.

What to watch: The staff will monitor Tiernan's recovery throughout the remainder of the preseason.
