Eddie Hearn believes that Amir Khan would be no match for Kell Brook at welterweight.
Hearn feels that Khan's inability to withstand his opponent's offence means that he would be vulnerable in the 147-pound division, and the promoter reckons that Brook would be able to beat the former four-time world champion.
"At 147 pounds, Amir couldn't live with Kell Brook. That's not taking anything away from Amir, [but] he's not a welterweight." Hearn is quoted as saying by BoxingScene.com.
"Khan has achieved a lot, more than many in their careers, but he is not looking good when he's getting hit and he's still getting hit.
"Khan is very entertaining to watch but I don't ever see him being a force at 147 because they will just walk him down and out strength him."
Khan won his last fight against Julio Diaz on points last month.
