DALLAS (AP) — SMU football player Teddy Knox has been suspended after being identified as the second driver along with Kansas City Chiefs receiver Rashee Rice in a high-speed, chain-reaction crash on a Dallas highway.

The school said Thursday it was made aware of an arrest warrant for Knox issued by Dallas police and declined to offer further details on the suspension, citing student privacy laws.

Police have said the warrants issued for the 21-year-old Knox included one count of aggravated assault, one count of collision involving serious bodily injury and six counts of collision involving injury.

The 23-year-old Rice, a former SMU player who won a Super Bowl with the Chiefs in February, also is facing one count of aggravated assault, one count of collision involving serious bodily injury and six counts of collision involving injury.
