Tyson receives OK to fight Holyfield

 NEW YORK (AP) -- The Mike Tyson-Evander Holyfield fight is back on track.
 Tyson's doctor has given the heavyweight fighter full clearance to resume contact training in preparation for his June 28 rematch against Holyfield.
 The rematch originally was scheduled for May 3, but was postponed when Tyson reopened a cut over his left eye originally sustained in his upset loss to Holyfield.
 John Horne, Tyson's co-manager, announced Monday that Tyson received clearance from Dr. Barry Markman to resume training.
 At the time of the postponement, Marc Ratner, head of the Nevada Athletic Commission, said he was told the cut had reopened and the former champion had stitches.
 It was the second time Tyson postponed a fight with Holyfield, and the latest in a string of fight postponements for the former champion.
 Bruised ribs forced Tyson to pull out of a date with Holyfield in 1991, and he postponed a fight last July with Bruce Seldon after a bout with bronchitis.
 Tyson also postponed a fight with Buster Mathis Jr. in November 1995 after breaking a thumb.
 Last Nov. 9, Holyfield stopped Tyson in the 11th round to win the heavyweight title.
 Holyfield will get at least $35 million for the June 28 fight, while Tyson is expected to make about $20 million.
