The Dallas Cowboys not only lost their opener to the Los Angeles Rams Sunday they also will be without tight end Blake Jarwin for the rest of the season.

Jarwin suffered an ACL tear in his right knee, according to Ian Rapoport, and is out until 2021.

Remember, the Cowboys let Jason Witten get away to Las Vegas via free agency.

Jarwin had 31 catches for 365 yards last season.

Add this to the loss to LB Leighton Vander Esch, who suffered a broken collarbone.
