Starting cornerback Donald Washington and reserve safeties Eugene Clifford and Jamario O'Neal did not take part, although they were seen running on the Woody Hayes Athletic Center field where practice took place near the end of the event.
When asked for comment, the only coach made available – assistant head coach and wideouts coach Darrell Hazell – did not divulge any specifics.
"Doing a little extra work today. That's about it right now. I'll let Coach (Jim) Tressel handle that one," he said.
When asked if there was anything that needed handling, Hazell replied, "Not really. Not at all."
Tressel was not made available to the media, but will be after Saturday morning's jersey scrimmage.
An OSU spokesperson said there were no suspensions or dismissals to announce.
Hazell noted that this was the first practice the three have missed this spring and that they had missed the entire practice.
Washington started all 13 games last year as a sophomore and made 39 tackles and an interception. O'Neal made 14 tackles as a junior and Clifford played in four games as a freshman, making eight tackles before an injury ended his season and earned him a probable medical redshirt.
Clifford also was suspended for the BCS National Championship Game.
Also very limited on the field was Ray Small, a junior wideout. The junior from Cleveland Glenville, who was third on the team with 20 catches for 267 yards and two touchdowns last season, was not limited because of injury according to Hazell but because of another decision.
Hazell added that Small is three-quarters caught up with the rest of the wideouts group and that he will see reps in tomorrow's scrimmage. Hazell also confirmed that Small had switched numbers from No. 4 to 82 as a reminder before praising the way he's handled the situation.
"He's done a good job here the last couple of days," Hazell said. "He's worked hard."
Wearing yellow jerseys were wideout Taurian Washington, cornerback/wideout Devon Torrence, wideout Jake Stoneburner, wideout Chris Roarke, corner Donnie Evege, tight end J.D. Larson, and offensive linemen Michael Brewster and J.B. Shugarts, who were seen drilling with one another. Linebacker Brian Rolle and wideout Brian Robiskie were wearing blue limited contact jerseys, although neither took part in any of the scrimmaging.
