Alexander Edler continues to rehab his back but according to Jason Botchford of the Vancouver Province, surgery has not been ruled out. Edler has had back problems throughout his NHL career and they flared up once again in September. Had there been a hockey season, Edler would still be out of action. Edler's back woes are a big concern to the Canucks as they chose not to re-sign him before the September 15 lockout. Should free agency remain the same once both sides settle, he can become a free agent after the 2012-13 season. He is a very good offensive defenseman but his long term back problems have to be a concern.
