Dean Lonergan, promoter for WBO welterweight champion Jeff Horn (18-0-1, 12 KOs), is not very happy with the recent news that Top Rank approached promoter Eddie Hearn to discuss the possibility of staging Terence Crawford vs. Amir Khan.

Crawford (32-0, 23 KOs), who is handled by Top Rank, is scheduled to face Horn on June 9th at the MGM Grand in Las Vegas.

Khan made his return this past weekend after two years of inactivity, as he easily knocked out Phil Lo Greco in 39 seconds. The contest was held at a catch-weight of 150-pounds, but Khan plans to campaign at the welterweight limit of 147.

Horn is coming off a banner year after shocking eight division champion Manny Pacquiao for the WBO title last July, and then coming back in the fall to score a knockout over Gary Corcoran in a voluntary defense.

The contest with Horn will be Crawford's first bout at the welterweight limit. Crawford was a former lightweight champion and unified all four of the main organizational titles at junior welterweight. Now he intends to go for his third divisional belt.

Lonergan is very offended that Crawford's promoter is already making moves to secure opponents in the coming future.

He promises that Crawford will never come away from the arena with the WBO title around his waist.

"Top Rank seem to forget that Crawford has a big fight on June 9. [Top Rank CEO] Bob Arum and his errant matchmakers are kidding themselves if they are looking past Jeff Horn, thinking Crawford is going to win that fight," Lonergan told Sky Sports.

"Maybe the whole welterweight division should wait and see the outcome of Horn against Crawford as a superstar from Down Under is about to emerge. With Manny Pacquiao and Randall Bailey already on his resume, Terence Crawford is going to be a nice scalp to add to it."
