Dallas also surprisingly cut veteran kicker Dan Bailey - the second most accurate in the National Football League since 2011 - and lost 11-time Pro Bowl tight end Jason Witten to retirement.
Especially when it came to their attack through the air, which appeared limited at best, as Cole Beasley finished the day as the Cowboys' top target, with seven catches for 73 yards in a 16-8 loss to the Panthers.
The Panthers limited the Cowboys to 60 yards and four first downs to take a 10-0 lead into the locker room.
George tweeted that Jones left the locker room quickly without comment as most reporters were interviewing running back Ezekiel Elliott.
Bailey's replacement, Brett Maher, missed his only kick at goal from 47 yards in the third quarter.
But while Bryant mainly tweeted about the Cowboys, he also shared his thoughts about the two teams he wants to play for this season - the New England Patriots and the Washington Redskins.
