Undefeated 25 yr old Heavyweight Tyson Fury (21-0, 15 KOs) will face 32 yr old Minnesota native Joey Abell (29-7, 28 KOs) on Saturday at Copper Box in London, England. The fight is scheduled to begin at 4PM ET. The Co-Main Event will feature another matchup of an English Heavyweight vs an American with the 32 yr old English Derreck Chisora (19-4, 13 KOs) vs the New Jersey native, 34 yr old Kevin Johnson (29-4, 14 KOs).
If Fury and Chisora each win their bouts, promoter Frank Warren has said they will face each other in a re-match in June of 2014. In 2011 Fury won a UD over Chisora.
The rankings I personally pay attention to are put out by Dan Rafael of espn.com. Rafael currently has Fury as the #9 Heavyweight in the world. The rankings can be seen here.
