FRISCO, Texas - Dallas Cowboys cornerback Trevon Diggs suffered a torn ACL in his left knee in practice on Thursday.
The two-time Pro Bowler was injured during a 1-on-1 portion of practice.
FOX 4 cameras saw the Cowboys corner earlier in practice working with fellow cornerback Stephon Gilmore and defensive backs coach Al Harris.
Diggs was later seen leaving the facility on crutches.
An MRI after practice confirmed that Diggs tore his ACL.
The team says a timetable for Diggs' return has not been established at this point, but he is currently expected to miss the remainder of the season.
On social media the Cowboys corner said "Thank you for all the prayers and I appreciate everyone for checking on me! This is just God’s Plan. I will be back and better!"
Diggs has had a sensational start to the season with an interception and a forced fumble.
He has allowed a 1.0 QBR to quarterbacks on passes thrown in his direction. In two games this season, he has allowed 26 yards on just two receptions.
Diggs signed a five-year, $97 million extension this summer.
The Cowboys will now have to rely on names like Daron Bland, Jourdan Lewis and newly-acquired Noah Igbinoghene, plus possibly a player or players they could acquire via trade to try to fill the huge void created by Diggs.
The Dallas defense had only allowed a league-best 10 points in two games.
The Cowboys take on the Arizona Cardinals this Sunday at 3:25 p.m.
You can watch the game on FOX 4.
