Luongo might play, and Henrik might not:

Sedin's ironman streak is the second-longest active streak, only 4 games shorter than Bouwmeester's.
Lack has played well against the Flames this season, and the Flames can't score on a shooter tutor at this point, so there's no point in rushing Luongo back, although, a slower-paced game could help him get his timing back.
If he plays, here's hoping he gets lit up and loses all confidence.
