Redskins rookie quarterback Dwayne Haskins missed the final play of his first career win Sunday because he was too busy taking “selfie” photos with fans.

“How do miss the last snap of a game because ur taking selfies,” tweeted Redskins legend Joe Theismann, who before the season gave Haskins his blessing to wear his former No. 7. “That’s unprofessional & wrong.”

Haskins was 13 of 29 for 156 yards (no touchdowns and one interception) in the Redskins’ home victory over the Lions before missing the kneel-down thanks to his poorly timed photo op.

Backup Case Keenum came into the game with Haskins out of the picture.

“I was so hype, I broke a water bottle,” Haskins told reporters. “I look up and we’re in victory. I thought the game was over with already, but I’ll get it next time.”

Interim head coach Bill Callahan said the team was looking for Haskins to take the snap.

“I think he thought the game was over,” Callahan said. “I think he thought it was over. So yeah, I’ll have to find out a little bit more.”

He added: “No, I don’t laugh at it. I’m happy we won. We’ll address that.”

Haskins, a former Ohio State star, has struggled in his first season and is 1-2 as a starter.
