Injured Melbourne star Cooper Cronk keen to catch a wave or two Cooper Cronk is in doubt for Melbourne Storm's season opener after a shoulder operation. Cooper Cronk enjoys a swim. COOPER Cronk's enforced layoff from rugby league has resulted in one of the game's weirdest press releases. Cronk has had off-season surgery on a nagging shoulder injury and is set to be out of action until Round 2 in March, forcing Melbourne Storm to field an untried halves combination after five-eighth Gareth Widdop's move to the St George Illawarra Dragons. Cronk would have been gutted at the enforced break but his coping mechanism has been revealed in a bizarre marketing campaign this week. Cronk is now spruiking alpha waves and its creator John Levine. "I spend a lot of time getting my mind calm before important matches," Cronk wrote on his website. Part of that battle is to empty the mind of noise. These CDs really work. I should also mention I have never met John and I buy them at full price like everybody else. Cronk and Levine are adamant alpha waves significantly improve healing, digestion, the immune system and concentration. Levine sent out a press release quoting Cronk's website and stated how chuffed he was to receive such high praise from the Dally M medallist. "Australian Professional Rugby League Footballer with Melbourne Storm, National Rugby League, is successfully using the Alphamusic of John Levine to help him concentrate before the big matches and to score!" the press release said. Melbourne coach Craig Bellamy said: "He has had an operation on his shoulder so that is the main reason he won't play in any of the trials."
