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).
Herrera sees contact
Right guard Anthony Herrera continued his ahead-of-schedule recovery from knee surgery. Herrera came off the physically-unable-to-perform list Monday but did only installation work. He was in full pads Tuesday and took some snaps with the first-team offense during 11-on-11 work. There is a chance Herrera could play in Saturday's preseason game at Seattle. If he plays, it would be for the first time since he was injured last November against Green Bay in the Metrodome.
Musgrave said a decision on Herrera playing Saturday was a couple of days away, but that Herrera looked good on Tuesday.
Perhaps because Herrera appears to be ahead of schedule, the Vikings appear to be working on building depth along the line. Chris DeGeare, who spent most of camp competing at right guard, is working at right tackle. Musgrave said the coaches were looking to gauge DeGeare's flexibility.
"I guess [the coaches] just want to see what I can do over at tackle this week," DeGeare said. "So I'm up for the challenge. Wherever I can contribute, that's a plus for me."
DeGeare played three years at guard at Wake Forest before playing his final season at left tackle. As a rookie last year, he played in eight games, and started the last five at left guard after Steve Hutchinson was injured.
• The Vikings are $376,354 under the $120 million salary cap, according to NFL.com. Only St. Louis has less salary-cap space, and the Rams are $822,036 over the cap. This comes despite the fact the Vikings have severed ties with left tackle Bryant McKinnie ($5.4 million cap hit in 20110 and safety Madieu Williams ($5.5 million) and reworked the contract of wide receiver Bernard Berrian ($1.9 million salary for 2011).
• Vikings owner Zygi Wilf, team President Mark Wilf and most of the rest of the ownership group were in town the past two days for their annual meetings.
