Boston striker Noel Whelan has admitted himself to a alcohol treatment clinic.
Whelan joined Boston in the summer of 2005
The 31-year-old former Leeds and Middlesbrough striker checked into the Sporting Chance charity, which was set up by former Arsenal player Tony Adams.
Sporting Chance chief executive, Peter Kay said: "The reason we're making this public is that Noel has nothing to hide and is facing up to his problems.
"It takes immense courage to say life has become a little bit tough and admit that you need some kind of support."
Boston chairman Jon Sotnick has vowed to stand by the striker.
"Along with everyone else at the club, I am hugely supportive of Noel and we will do everything we can to help ensure he makes a full and speedy recovery.
"I don't know the exact details of Noel's illness but he has clearly recognised he needs to get himself sorted out and I've got enormous respect for that.
"There's absolutely no question that we wouldn't support him through his rehabilitation, and hopefully he can return to action fitter than ever."
