Stamkos practiced with his teammates on Thursday as they prepared for a game Thursday night against the New York Islanders. The centre had been skating on his own, or briefly joining the team on the ice at the end of workouts.
A member of Canada's Olympic team, Stamkos remains confident that he will be able to play with the Lightning and then participate in the Sochi games next month.
"It's not a full practice, but to be able to get out and not have to go off early or not have to wait until the end to go on, I wanted to go and try it," Stamkos said. "It's the best it's felt."
Stamkos has been out since he was injured Nov. 11 at Boston and needed surgery.
"A lot of this is physical and how you feel," Stamkos said. "But there is that mental element. The power of the mind is very strong and I've really come to understand that right now. This is another step closer."
Stamkos had 14 goals and 23 points in 17 games before the injury.
"Every day he's getting closer," Lightning coach Jon Copper said.
