The Facts: Mathis is still dealing with injuries suffered in a recent motorcycle accident, but he did join his teammates on the field for the first time on Monday. "He's not full strength," Gary Kubiak said. "He was hobbling around. But he really has to catch up and help us as a receiver as well as a returner. That's very important to this team."

Diehards Line:Mathis was a Pro Bowl returner as a rookie last season, but rarely was included in the offense. Kubiak hopes he can help Mathis become a wide receiver threat. Lots of speed, not much polish.
