Watt had surgery to repair a herniated disc. And here is the scary thing about a herniated disc --- the time table to get back is all over the place, from 6 to 8 weeks to ten weeks and even longer.

We caught up with teammate Devon Still, who was at Texas Children's Hospital Friday, visiting families battling cancer. He says JJ is going to be just fine.
"I think what he's going through is not going to stop him from making an impact on the team," said Still. "He's our team leader. He can do that on the field or off the field. We have to step it up and take care of business until he's ready to be on the field."
