Gavin Henson has admitted that he is considering his future in rugby as a result of the ankle injury that has thrown his hopes of a place on the Lions tour this summer into disarray.

The Wales and Ospreys utility player has been ruled out for two months with an ankle problem, and says his fitness problems over the past few years have been "soul-destroying".

"Those thoughts run through my head," he told BBC Sport when asked if he questioned his future in the game. "When I get knocked out with an injury, it is soul-destroying. Is it worth it?"

Henson missed the start of the Six Nations with a calf strain and suffered throughout the autumn with an achilles injury. On Saturday he picked up his latest knock, damaging ligaments in his right ankle in the Ospreys' 17–0 EDF Energy Cup defeat to Gloucester, a problem that jeopardises his place in Ian McGeechan's Lions squad for the tour to South Africa.

"It is a complete nightmare again, I can't believe my luck," said Henson. "Everyone sees the press I get every time I get injured. It is tough for me and my family – it is hard to take. I'm pretty down and depressed about it at the moment. Maybe I'm cursed."

"The injury will probably rule me out of the Lions tour, to be honest. It'll be a pretty brave decision to take me now as I'm probably a bit of a liability with the way I am with my injuries, this season is probably a miss now."
