Prior to a crucial game Sunday against the Anaheim Ducks, the Oilers reported Nugent-Hopkins will travel to Cleveland to have his shoulder examined, with surgery a likely possibility.
The Oilers need a win to keep their hopes for a spot in the Stanley Cup Playoffs alive. They enter the game 12th in the Western Conference, seven points behind the eighth-place Columbus Blue Jackets with five games remaining.
Nugent-Hopkins, the first pick of the 2011 NHL Draft, had four goals and 20 assists in 40 games this season. He missed time earlier this season with an injury to his left shoulder, and missed 20 games last season with a shoulder injury.
