Solis was wrapping up Cardinal running back Anthony Wilkerson early in the third quarter when he and a teammate hit helmets. Solis, a freshman from Thousand Oaks, Calif., stayed down for quite some time as medical personnel loaded him onto a stretcher as a precaution.
The team announced he had movement in his limbs.
Solis has missed two games this season because of injury. He also didn't play in the season opener against Colorado State.
