PFT is reporting that Schaub is out for multiple weeks with a foot injury and Schefter is apparently hearing it's a Lisfranc injury. That sucks for Kubes. He has one of the best teams in the AFC this year when healthy and he's built it right in a team that can run the ball but can also take to the air when necessary. Luckily they have a bye then Jax so two weeks to get it figured out.
If there was ever a time for Leinart to succeed, this is probably his best chance.
