Tyson Fury deserves credit for raising awareness of mental health issues in sport, says former WBA lightweight world champion Anthony Crolla.
"For him to come forward takes a lot of courage," Crolla told BBC Radio 5 live.
"Hopefully it helps raise awareness and gives other people, sports stars, encouragement to come forward.
"He needs extra credit. Tyson is a big, strong man and he comes from a community where they are very proud men."

Fury, who is part of the Traveller community, inflicted Klitschko's first defeat since 2004 to become world champion, but Crolla says he may not have been prepared for what came next.
"I certainly wouldn't say it came at the wrong time, because he gave a great performance and it was a memorable win," added Crolla, 29.
"There was a lot of other things in the media for the wrong reasons after, and I'm sure that didn't help.
"I don't know if he expected what was coming after it."
