NEW ORLEANS (AP) - Devon Walker's closest Tulane teammates cite his drive to play his first two seasons without a scholarship, all while pursuing a difficult degree, as reasons they believe he has the courage to cope with his spinal injury.

Walker, a senior safety, is due to graduate with a degree in cell and molecular biology in May.

Tulane cornerbacks Ryan Travis and Kendrick Washington say they miss Walker and eagerly await a chance to speak with him, but remain confident he'll lead a fulfilling life even if he winds up with physical limitations.

The Green Wave returned to practice on Tuesday for the first time since Walker fractured his spine during a game Saturday at Tulsa, where remains hospitalized. Doctors say it's too early to know the long-term effects of his injury.
