Tyson physically fit for Holyfield

 LAS VEGAS (AP) -- Mike Tyson underestimated Evander Holyfield once. He says he won't make the same mistake twice.
 "I have a great deal of respect for his boxing skills," Tyson said. "With that respect alone, I'll be a lot more intense for this fight."
 Whether Tyson's intensity can help him in the rematch against Holyfield remains to be seen. But he showed Friday that he should be in fine physical condition for the once-postponed June 28 rematch.
 All that remains is for Tyson to get himself mentally prepared to meet a fighter who knocked him out the first time they got together in the ring.
 "My confidence is never shaken by anything," Tyson insisted. "I'm going to go in there and fight him like I knocked him out the first time."
 Tyson worked out before the media Friday for the first time since Holyfield beat him last November, then stood and patiently answered questions about how he was preparing for the fight that could likely define his boxing career.
 Losing to Holyfield in the 11th round of their Nov. 9 fight was certainly something that "opens your eyes," Tyson conceded, though he refused to call the rematch crucial to his boxing career.
 But Tyson, who turns 31 two days after the bout, said it was a fight he had to win.
 "I feel I have to win it for myself," Tyson said. "I want the title back."
 Tyson, who normally trains behind closed doors at a local gym, went through a 40-minute workout in a ballroom at the MGM Grand Hotel that included three rounds of hitting pads held up in the ring by camp member Stacy McKinley.
 The purpose of the session was to dispel rumors that Tyson had further injuries since a cut next to his left eye forced the original May 3 rematch to be postponed or that he wasn't training properly.
 "As far as I know it's going on," said Tyson, who will earn at least $20 million for the rematch. "I'm in great shape."
 Tyson certainly looked fit as he threw savage left and some hard rights to McKinley's pads and to a flak jacket around his midsection. Promoter Don King watched closely from nearby.
 "We're putting the rumors to rest and saying that the fight will take place," King said. "They say he's fat, he's out of shape, he's out carousing. You can be the judge. We want to stop the rumors."
 Tyson was attentive to trainer Richie Giachetti, brought back to camp following the loss to Holyfield, as Giachetti instructed him on combinations of punches to throw.
 Giachetti seemed to be trying to get Tyson to throw more jabs, which he did little against Holyfield, and pressure his opponent more.
 "How's my balance look, is it all right?" Tyson asked at one point.
 Toward the end of the brief session, Tyson made McKinley flinch when he hit him with a right to his padded midsection.
 "Can he (Holyfield) take that, ladies and gentlemen?" Giachetti asked the small crowd. "No."
 Tyson, who started sparring on Monday for the fight, said he has had no problems with the eye he cut in training the first time for the rematch.
 "As long as it holds up until I get in the ring, I'll be fine," he said.
