Burns was presented Monday as the newest fighter for promoter Matchroom, causing Frank Warren to claim a breach of contract and announce his intention to sue the 29-year-old Scot for "substantial damages."
Warren says "Burns is under binding promotional and management contracts."
Burns (35-2, 10 knockouts) hasn't fought since retaining his belt against Kevin Mitchell in September but had been due to fight Vazquez at Wembley Arena on April 20 in a postponed contest.
Burns says "I just felt over the last year or so things hadn't been working out" as "there were a few issues that needed working out."Suggest a correction
