Longtime NHL referee Mike Leggo is retiring. And the Los Angeles Kings and Arizona Coyotes weren't going to let that go unacknowledged at his final game on Sunday.

Leggo, perhaps best known for his viral "You can't do that" penalty call from 2013, is hanging up his skates at age 52 after officiating over 1,200 games since the 1996-97 season.

The Arizona Coyotes, led by captain Shane Doan, all lined up to shake Leggo's hand after the game in a classy gesture.

The Kings met with Leggo before the game and gave him an autographed jersey from the team.

Leggo was also honored on the ice, getting a nice ovation from the Staples Center crowd. His family was also in attendance.

In his 20 seasons, Leggo has worked 1,213 regular season games and 42 Stanley Cup Playoff games.
