Hamzah Sheeraz (21-0, 16 KOs) dropped Tyler Denny (19-3-3-, 1 KO) in the first round and stopped him in the second, swiping his EBU European middleweight title Saturday on the Daniel Dubois-Anthony Joshua undercard at London's sold-out Wembley Stadium.

Joshua Buatsi (19-0, 13 KOs) overwhelmed Willy Hutchinson (18-2, 13 KOs,) flooring him twice, and somehow still walked away with only a split decision win. At least Buatsi also took home an interim light heavyweight title for his troubles.

Junior lightweight titleholder Anthony Cacace (22-1, 8 KOs) defended his belt in a unanimous decision over former featherweight titleholder Josh Warrington (31-4-1, 8 KOs), who left his gloves at center ring after their fight to signal his retirement from boxing.

Middleweight Ishmael Davis (13-1, 6 KOs), a late replacement, gave an good account of himself but took his first professional loss in a majority decision that favored Josh Kelly (16-1-1, 9 KOs).

Highly touted lightweight Mark Chamberlain (16-1, 12 KOs) was dropped and defeated for the first time in a unanimous decision to Josh Padley (15-0, 4 KOs).
