The lost more than their first game of the 2020 season on Sunday night. Amid a 20-17 defeat at the hands of the , the NFC East favorites saw two different starters -- Joe Thornton Jersey tight end and middle linebacker Leighton Vander Esch -- exit early due to injuries, and it doesn't appear that either one will be back anytime soon.Vander Esch was the first to exit due to a collarbone i sue, and the Cowboys have confirmed the former All-Pro . The linebacker, who did not return after leaving halfway through the second quarter of Sunday's lo s, required surgery for the injury, but there's a bit of a silver lining to the dark cloud surrounding Vander Esch.

That would see him potentially return before mid-season, and help the Cowboys in a potential late season run toward the playoffs.Jarwin, on the other hand, is after suffering what's feared to be a torn ACL on a non-contact play.

A nerve-related neck i sue sidelined him for seven games in 2019, and Sunday night's injury forced longtime reserve -- who was already filling in for , who's on injured reserve -- into first-team duties. At TE, the Cowboys could be forced to look outside the organization for reinforcements, especially considering how much of a role Jarwin figured to play as one of top pa s targets over the middle. In the meantime, No. 2 will likely be in line for additional reps. Chris Tierney Jersey
