Detroit Red Wings prospect Mitch Callahan received some unexpected dental work on Wednesday, courtesy of an errant puck, and decided to share a photo of his mouth on his Twitter account.

Callahan, who plays for the AHL’s Grand Rapids Griffins, suffered the injury during the first period of the team’s 6-1 victory over Iowa Wild on Wednesday, MLive.com reports. The 22-year-old perched in front of Wild goaltender Johan Gustafsson in an effort to deflect the puck into the net, only to be hit in the mouth by a teammate’s shot.

The Red Wings minor leaguer suffered severe bleeding and the loss of several teeth. Callahan’s teammates did their best to locate as many of his missing teeth as possible on the ice.

The young player, who was already missing his two front teeth, lost about four additional teeth, MLive.com’s Peter Wallner notes. He was taken to a local hospital for treatment.

“I saw him come back (and then) I saw his teeth come back with him,” Callahan’s teammate, Trevor Parkes, told MLive.com. “Couple of us had some shaky stomachs after that.”

Still, Callahan wasn’t deterred by the horrific injury. The forward posted a photo of his still-bleeding mouth, with several missing teeth and a badly cut lip, to his Twitter account, along with the caption, “Ouch.”

Callahan’s Twitter selfie was a bit hit on the social media site, garnering over 5,000 retweets and 4,000 favorites. But Grand City Griffins head coach Jeff Blashill disapproved of his player’s in-game post.

“Shame on me for not having a more direct statement on that,” he said. “But I just think we have to be real careful about what we put on social media.”

Callahan has been one of the Griffins’ most effective players this season—he’s second on the team in goals and has recorded 11 points in his last eight games, MLive.com notes.

The Twitter photo of his injured mouth can be viewed below. WARNING: the image is graphic.
