Hakanpaa (lower body) is expected to miss Game 2 versus Vegas on Wednesday, according to Brian Rea of Bally Sports Southwest.
Hakanpaa hasn't played since March 16 due to the injury. He had two goals, 12 points, 33 PIM, 196 hits and 123 blocks in 64 appearances during the regular season. Once Hakanpaa is healthy, he might replace Nils Lundkvist in the lineup.
