Theoren Fleury will attempt a comeback to the NHL, TSN reported on its website Friday.

Fleury, 41, hasn't played since 2003 when he was with the Chicago Blackhawks — the last stop of a 15-season NHL career that also included stays with Calgary, Colorado and the New York Rangers.

Fleury remains under suspension for violating the league's substance abuse policy, according to the report, and would need the approval of NHL and players' union doctors and commissioner Gary Bettman before he can play again.

The report said Fleury decided in February to try a comeback and has been working with a personal trainer.

Fleury recorded 1,088 points (455 goals) in 1,084 regular-season games, and added another 79 points (34 goals) in 77 playoff contests. He was a member of the Flames' 1989 Stanley Cup championship team and won Olympic gold with Canada in 2002.
