EDINBURGH super middleweight John McCallum is seeing stars after securing a glamour bout on the undercard of former four-weight world champion Roy Jones Junior's comeback fight on February 17.

McCallum was recommended for the New York bill by 47-year-old Jones' opponent for the vacant WBF world cruiserweight crown, Bobby Gunn.

The 28-year-old impressed Gunn when he sparred with the former bare knuckle boxer during a recent visit to Gleason's Gym in Brooklyn.

McCallum said yesterday: "I sparred with several top pros at various gyms, including Gleason's, when I was across in the States on a training trip in October.

"They included Ossie Duran, who beat Scotland's Colin McNeil for the Commonwealth super-welterweight title, and Bobby.

"I handled them and others quite comfortably and I think I surprised and impressed a few people at the same time.

"Bobby has been pursuing a fight with Roy Jones for a long time and although Jones is past his best it will be a privilege to appear on the same bill as such a legend."

Jones, who last fought in 2011, is the only boxer to have launched his career as a light-middleweight before going onto to be crowned world heavyweight champion.
