Former world heavyweight champion David Haye will be joined by his unnamed opponent at a press conference in London on Tuesday.
The 35-year-old, who has not fought since beating Dereck Chisora in 2012, announced his return to boxing last week.
Haye's opponent is yet to be named, but will be unveiled at the O2 Arena alongside the British boxer tomorrow.
Haye, who held the WBA belt between 2009 and 2011, has been training with Shane McGuigan.
