The Geelong forward is in danger of missing another year of footy because of the broken ankle that ruined his 2001 season.
Complications have forced Snell to rest the ankle completely and with just 11 rounds remaining, he rates himself only a 50-50 chance to make it back this year.
``I've had enough,'' a frustrated Snell said yesterday.
``I just want to get over it and get out there and play, especially after watching a game as exciting as last weekend's.
``But more than that, I want to get out of this pain-free.
``Footy is a consideration, but to be able to walk around properly for the rest of my life is important.''
Snell, 24, has not played since breaking his leg and dislocating his ankle in a marking contest against Melbourne in round three last year.
The force of the impact pushed his entire ankle joint through his skin, leading doctors to liken it to damage caused in a high-speed motorcycle accident.
The gruesome injury ruled him out for 2001 but he was on track to resume earlier this season. Remarkably, he was just one week away from playing again when trouble struck.
He had an arthroscope to remove scar tissue from the ankle and give him more flexibility, but the operation also heightened the pain from a bone spur in the joint.
``I noticed the bone spur more because of that extra flexibility and I couldn't run with it,'' Snell said. He underwent further surgery to remove the bone spur eight weeks ago but the pain has remained.
``I'm in limbo,'' Snell said.
``It's still sore everyday, and a bit swollen.
``Before the operation I was probably 80-20 to play again this year, now I'm only 50-50.''
Snell will visit a Melbourne surgeon today and a specialist in Sydney next week in a last ditch effort to play again this year.
