No timetable for the return of the NHL's co-leader in goals and assists has been established, the Lightning indicated.
General Manager Steve Yzerman said Monday Stamkos suffered a broken right tibia during the Lightning's 3-0 loss in Boston earlier in the day and would be out indefinitely.
The 23-year-old Stamkos, who is tied for the NHL lead in goals (14) and points (23), was carried off the ice on a stretcher after slamming his leg into a goalpost while tangled with Boston defenseman Dougie Hamilton.
"The biggest concern for me, and the rest of the Lightning, is that decisions are made in Steven's best long-term interest, and we feel this is the appropriate course of action," Yzerman said.
