Harvin gave reporters the thumbs-up after practice, but declined to address his injury status.
Vikings offensive coordinator Bill Musgrave said he wasn't sure what Harvin's injury was and it could be a potential flare-up of the rib injury Harvin suffered last week during the Mankato portion of training camp.
"I'd have to check with Eric [Sugarman, head athletic trainer]," Musgrave said shortly after practice. "I don't know if he still has his ribs bothering him, but we'll check I'm sure in our post-practice report."
Also sitting out Tuesday's practice were tight end Visanthe Shiancoe (hamstring), linebacker Heath Farewell (hamstring), linebacker Kenny Onatolu (foot) and safety Simeon Castille (hamstring). Shiancoe and Castille ran up and down the sidelines for conditioning during the early part of practice.
"I did try to give Shank a hard time and remind him that we did draft a guy [Kyle Rudolph] in the second round and he's not looking too bad," Musgrave joked. "But Shank is coming back as fast as he can and we're looking forward to getting him back, hopefully next week. If not next week, I'm sure he's working like crazy to get out here and get with his teammates."
Linebacker Jonathan Gilmore (unknown) also left practice and didn't return.
HERRERA INCREASING WORKLOAD
Guard Anthony Herrera returned to practice on Monday for the first time, but on Tuesday he increased his reps and worked in with the first-team offense on a rotational basis at right guard with Scott Kooistra. Herrera is returning from a torn anterior cruciate ligament suffered Nov. 21, 2010. Just last week head coach Leslie Frazier indicated that Herrera wasn't close to returning.
On Tuesday, Musgrave said he wasn't sure if Herrera would be able to contribute in Saturday's second preseason game.
"I don't know that we know at this point. We've still got a few days 'til Saturday, but so far so good the first couple days that he's been out here," Musgrave said.
"I think he looked good. I think he, like a lot of us, is just getting back into football shape. It's definitely a process, though."
Herrera was still on physically-unable-to-perform (PUP) list for the preseason opener on Saturday. He started the first 10 games last year at right guard, but missed the final six after being placed on injured reserve.
Second-year player Chris DeGeare started in Herrera's spot Saturday against the Titans, but has been practicing mostly at right tackle this week as the Vikings look at their options across the offensive line.
"I thought DeGeare, like the rest of our offensive line, did a good job," Musgrave said. "At times, when we had pressure it wasn't really due to the O-line, it was due to the timing of the quarterbacks and the receivers, not getting the ball when they should have. The O-line did a respectable job. They'll look to improve on it, but it was a respectable job for them."
VIKINGS TIGHT AGAINST THE CAP
The Vikings have less than a million dollars left in salary-cap space – $376,354.00 to be exact, according to NFL.com.
NFL teams had to be in compliance with the salary cap by the official start of the new league year. Because of the delay in getting a collective bargaining agreement ratified, that wasn't until Aug. 4 this year. By releasing safety Madieu Williams and left tackle Bryant McKinnie and restructuring the contract of receiver Bernard Berrian, the Vikings were able to get under the cap by the deadline.
The Vikings took advantage of a special cap credit this year that gave teams the option for up to $3 million in additional cap room by taking up to $1 million off the cap charge for up to three players with five or more accrued seasons. That credit will drop to $1.5 million next year with a maximum of $500,000 per player. So, in essence, the salary cap is $123.375 million this year.
The cap is listed at $120.375 million, but that doesn't include the special cap credits allowed this year. Only four teams have less than $1 million in cap space, according to the report.
The Bears have $19,342,968.00 in cap space, the Lions have $995,047.34, and the Packers have $12,736,997.00, according to NFL.com. On average, NFL teams have $11,053,871.70 in space, according to NFL.com.
