テレンス・クロフォード
On 31 May 2016, Top Rank promoter Bob Arum announced that Ramírez would fight on the undercard of the Terence Crawford-Viktor Postol unification fight on 23 July. Ramírez (34–0, 24 KOs), of Mexico, would have been making his first title defense against Germany's 28 year old Dominik Britsch (32–2–1, 11 KOs). Britsch had won four fights in a row since an eight-round decision loss in 2014, was about to take a big step up in competition. On 6 July, Ramírez suffered a hand injury while training, which ultimately called off the world title fight. Ramírez had a successful hand surgery and according to promoter Bob Arum, he should be able to make a ring return by the end of 2016.
