Point was injured in the first round series against Toronto, wherein 7 games, he tallied 2 goals and 4 points. In game 7, he suffered a lower body injury that's kept him out of the lineup until now.

It rarely happens, but this year, the two best teams will compete against each other for the Cup, and Point will be another contributor for the Lightning to turn the series in their favour.
As Jon Cooper said in the first round series against Toronto, the Lightning are knocking on the door of greatness with their opportunity to achieve the three-peat. Why shouldn't they barge right through that door?
