Lightning star Steven Stamkos on Sunday had an MRI exam on his injured left knee that general manager Steve Yzerman said showed "nothing of significance."
Stamkos said he hyperextended the knee slightly when checked by Panthers defenseman Filip Kuba with 1:10 left in the third period of Saturday's 5-3 season finale loss.
"At the time you don't know," Stamkos said Monday when asked if he had been worried about the injury. But the doc checked it out and it should be no problem, nothing major."
Stamkos, 23, whose 29 goals were second in the league, flies to Sweden Tuesday to play for Canada at the world championship.
As for another season out of the playoffs, Stamkos said he is disappointed.
"This team, we have the group in here, I know we do," Stamkos said. "We have the leadership. We have the young talent. We have the guys who have won it before knowing what it takes. It's just a matter of putting it all together. It is easier said than done. It wouldn't be frustrating if we knew we couldn't do it. It's not an impossible task. We know we can do it. We've done it in the past. That's why it's frustrating."
