Former British and Commonwealth champion Willie Limond has died at the age of 45, the St Andrew's Sporting Club has announced.
Limond fell ill last week amid preparations for a fight.
A statement from the Scot's boxing club read: "Everyone at St Andrew's Sporting Club are shocked and deeply saddened at the loss of our friend, Willie Limond.
"Willie was not only a legend of the sport, but an infectious character who will be greatly missed by us all.
"Our thoughts and prayers are with Jake, Drew, Macy and the rest of the Limond family at this time."
Former opponent Curtis Woodhouse was among those to pay tribute to Limond.
Limond beat Woodhouse to retain his Commonwealth light-welterweight title at Glasgow's Braehead Arena in 2014.
Woodhouse posted on X, formerly Twitter: "Absolutely devastated to hear the news of the passing of Willie Limond, a great fighter and a great man.
"We stayed in touch after our fight and always had a laugh together. Absolutely gutted. Rest In Peace champ."
