The Nashville Predators forward held up a funny sign to celebrate his brother Cal O’Reilly’s 1,000 th AHL game at the Allstate Arena in Rosemont, Illinois. “Congrats on having less teeth than me,” Ryan’s sign said.

The Milwaukee Admirals lost to the Chicago Wolves on the road Thursday afternoon. Cal O'Reilly played in his 1,000th AHL game.

Predators forward Ryan O'Reilly made the drive to Chicago to support brother Cal, who plays in game No. 1,000 in his AHL career on Thursday.

On Thursday, as his brother, Cal, was set to become just the ninth player in American Hockey League history to play in 1,000 games, Nashville’s alternate captain was there, ice level, sporting a Milwaukee Admirals “O’Reilly” jersey and holding poster over his head that read, “Congrats on having less teeth than me.”
