FRISCO, Texas -- The Dallas Cowboys fear that star cornerback Trevon Diggs has a torn ACL in his left knee, sources told ESPN's Adam Schefter.
Diggs suffered the injury Thursday during a 1-on-1 drill in practice and was briefly spotted inside The Star on crutches, sources told ESPN.
"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 $21.25 million signing bonus and $42.
