McEwan has lost his last two bouts in stoppage defeats, the first to Irishman Andy Lee in Connecticut and the second to Peter Quillin in Mexico, having won his first 18 paid fights in America.
The former Clovenstone amateur star admitted: “Having lost twice back-to-back means I’m right back at square one in American boxing terms.
“I have been offered an eight-round undercard bout on February 11 in Las Vegas which I will accept and train for at Freddie Roach’s Los Angeles gym. But I have come to the conclusion that when my contract with Golden Boy ends in June then I will be better returning to the UK.
“I’m confident I could win a British title and have more meaningful fights but to do that I must come back home to Scotland and fight regularly in British rings.”
Meanwhile, Edinburgh’s Celtic super-middleweight champion Kenny Anderson hasn’t given up hope of facing Londoner George Groves for his British title in Edinburgh.
Rival promoter Frank Warren has made a purse bid to stage the Groves v Anderson title clash on London on March 3 but Anderson’s manager Steve Woods insisted today: “Frank Warren has intimated that he wants to put Groves v Anderson on in London on March 3 but we have been told by our promoters Matchroom that if Sky Sports back the Matchroom bid, then we will be in with a shout of winning the bid and seeing Kenny fight Groves for his British title in Edinburgh.”
