Stamkos can now be considered day to day, coach Jon Cooper said. The Lightning host the Montreal Canadiens on Saturday and Dallas Stars on Sunday to close a four-game homestand.
"I don't see him playing against Detroit," Cooper said. "But after that I'd say it's getting really close."
The Lightning (37-29-9) have won three straight and are three points behind the Boston Bruins for the second wild card into the Stanley Cup Playoffs from the Eastern Conference. The Lightning have one game in hand on the Bruins, but Boston has five more wins in regulation or overtime, which would be the first tiebreaker at the end of the season.
Stamkos said despite wanting to return immediately he isn't going to let the standings dictate his timetable and doesn't want to be a liability on the ice if he doesn't feel 100 percent.
"I think you know me well enough to know that I want to be out there at all times and be a difference-maker," the Lightning captain said. "It's hard this time of year not to be involved, but the guys have played great as of late. Just being around a lot more in the past couple of weeks and competing in practice gives me the itch, for sure. I want to get back as soon as possible. But nothing changes in regards to me needing to feel the way I want in order to play my game out there."
