Eubank, 33, was scheduled to cross gloves with Conor Benn in October. The fight was canceled after it was revealed that Benn had recently tested positive twice for doping.
Smith, who was a welterweight world champion last year, has two fights this year. He last fought in September, defeating Hassan Mwakinho by TKO.
As part of the same evening, a fight between Richard Riakpore (15-0, 11 KOs) and the former two-time world heavyweight champion Krzysztof Głowacki (32-3, 20 KOs) should take place. Previously, Eubank's fight with Smith and the entire London tournament was scheduled for December 17th.
