Dez Bryant and Jason Witten fight on sidelines (GIF)

Dez Bryant’s unstable emotions were on full display Sunday during the Dallas Cowboys’ 31-30 loss to the Detroit Lions.

Bryant caught just one pass in the first half of the game — a one-handed touchdown grab to make it 10-7 Dallas before halftime. He may have been upset about how little action he was seeing, because he had a meltdown on the sidelines late in the third quarter. He yelled at Tony Romo and some of his coaches. But after the Cowboys a 60-yard touchdown to go up 20-10, he seemed to be doing much better and even gave Romo a pat on the butt. Then he seemed thrilled after scoring a 50-yard touchdown in the fourth quarter to make it 27-17. But all those positive emotions quickly disappeared after the Cowboys blew the lead.

Despite being up 30-24 with 1:02 left, the Cowboys lost the game after allowing the Lions to go down the field and score the winning touchdown. As the game was slipping away from Dallas, Dez had another meltdown on the sidelines and was confronted by tight end Jason Witten, who tried putting him in check.

It was such a childish display by Dez. Is he the only player on the Cowboys? Is he the only guy who was furious that they blew the game? He sure acted like that was the case. And he also acted like the game was already over even though Witten was reminding him they still had time left.

Here was his meltdown on the sidelines earlier in the game:
