"Alex will play tonight," coach Peter Laviolette said. "To be honest, I haven't really noticed anything different. He was a full participant, he wasn't held out of anything and he competed at full-go.
"He's good to go."
Ovechkin, 36, sat out the final three games of the regular season with an upper-body injury suffered when he tripped over the stick of Toronto Maple Leafs goaltender Erik Kallgren on April 24 and slammed into the boards with his left shoulder.
He has missed 27 games over his 17-year NHL career to injury and has never missed a playoff game.
Earlier this season, Ovechkin passed Jaromir Jagr (766) for third on the career goals list. He scored 50 goals this season for the ninth time in his career, tying Wayne Gretzky and Mike Bossy for the NHL record. Ovechkin's 780 career goals trails only Gordie Howe (801) and Gretzky (894).
