FRISCO, Texas -- Dallas Cowboys star cornerback Trevon Diggs left Thursday's practice because of an injury to his left knee.
Diggs suffered the injury during a 1-on-1 drill and was briefly spotted inside The Star on crutches, sources told ESPN. He was scheduled to have an MRI to determine the severity of the injury, according to sources.
"Some of you saw him leaving the field, so prayers to him," Cowboys quarterback Dak Prescott said. "Simple as that."
Diggs signed a five-year, $97 million contract extension with the Cowboys during training camp -- a deal that included a $21.
