Florida receiver Percy Harvin was limited in practice Tuesday because of Achilles' tendinitis.  Coach Urban Meyer said it was unclear how long the injury would affect Harvin, who emerged last season as one of the team's big-play threats.

"It's just a pain in the butt," Meyer said. "It's frustrating for him."

Harvin, a sophomore, had 428 yards rushing, 427 yards receivingand scored five touchdowns last season for the national champion Gators.  He earned Most Valuable Player honors in the Southeastern  Conference championship game, totaling 167 yards of offense and scoring two touchdowns. He was also a standout in the national title game against Ohio State, catching nine passes for 60 yards and adding 22 yards rushing and a score.

Meyer says Harvin "should " be ready for the Sept. 1 season opener against Western Kentucky.

The 5-foot-11, 181-pound Harvin missed part of fall practice last year with a hip flexor and then sat out one game and was slowed in several more because of an ankle sprain.
