A tough break for the Toronto Maple Leafs after Andreas Johnsson collided with teammate Kasperi Kapanen midway through the first period of Thursday night's game against the Dallas Stars. You can see the play below.

According to Sportsnet's Chris Johnston, Johnsson needs surgery on his knee and will miss the next eight weeks, which pretty much knocks him out for the rest of the regular season.

Johnsson has been having a pretty good season with the Leafs. The 25-year-old has eight goals and 13 assists in 42 games. He missed games earlier this season due to a leg injury.
