"Percy Harvin left practice, was tended to in the shelter that adjoins the Winter Park fields, then watched the rest of the Vikings' workout from the sidelines Tuesday.

Vikings coach Leslie Frazier did not address the media. Offensive coordinator Bill Musgrave did, but he was not sure of the receiver's situation immediately following the workout.

"I don't know if he still has his ribs bothering him or not," Musgrave said.

Harvin left practice Aug. 8 because he was winded and had sore ribs. Tuesday, he left the field and received medical attention from head athletic trainer Eric Sugarman. "I'll be good," Harvin said while flashing the thumbs-up sign as he left the field after practice ended.

Harvin has been in relatively good health this camp, especially when contrasted with the issues he has dealt with in the past. His first two seasons were plagued by migraines.

Rookie linebacker Jonathan Gilmore left the field on a cart early in the afternoon session. Among those who sat out practice were tight end Visanthe Shiancoe (hamstring), linebacker Heath Farwell (hamstring), defensive end D'Aundre Reed (calf) and cornerback Simeon Castille (hamstring)."
