Arizona State junior safety Riccardo Stewart returned to Tempe on Sunday morning after spending Saturday night in a hospital in Pullman, Wash., recovering from a neck injury sustained against Washington State.
Stewart lost feeling in his left arm after making a tackle late in the fourth quarter of ASU's 34-19 loss.
He was taken to Pullman Memorial Hospital for tests and remained overnight to undergo a CT scan, magnetic resonance imaging test and X-ray.
Coach Dirk Koetter said Stewart will have another MRI.
Doctors are calling the injury a bad stinger (neck numbness).
Stewart, accompanied by team physician Steve Erickson, left Pullman around 5:30 a.m. Sunday. He experienced flulike symptoms and was sore and tired.
While Stewart was at the hospital, teammate Skyler Fulton's family, former ASU assistant coach Robin Pflugrad and his family, Washington State coach Bill Doba and Cougars quarterback Matt Kegel paid visits.
"I feel fine," Stewart said in a statement. "But I am a little sore. But nothing serious. I would like to thank Dr. Steve Erickson and the rest of our medical staff for helping me, as well as the medical staff at Washington State University.
I am thankful to have such a caring Sun Devil family behind me."
A three-year starter, Stewart has a history of neck and shoulder problems.
