TAMPA — The Bucs couldn't wait to have DE Adrian Clayborn back this season. But six workouts into training camp, the only thing he might be able to practice is patience.
Clayborn, who tore his right ACL in Week 3 last season at Dallas, strained his groin during individual drills Wednesday and did not finish practice.
Coach Greg Schiano said he did not know the severity of the injury but it was not expected to sideline Clayborn for long.
"He's incredibly frustrated, obviously, after being out all that time with the surgery. He just gets it rolling again, and now something is holding him back," Schiano said. "But that's the way life goes.
"He's just got to keep battling, and he will."
The Bucs did see some injured players reach mileposts Wednesday. CB Darrelle Revis did coverage drills against a live receiver, Terriun Crump, for the first time since tearing his left ACL in Week 3.
"He'd been doing everything just on air," Schiano said. "Now we actually put a receiver there with him, so it was good."
G Carl Nicks, who missed the second half of last season with a toe injury, did one-on-one pass rush drills.
"He did a couple reps in a real period," Schiano said. "You've got to see how he responds then move him up."
TWO-MINUTE IMPROVEMENT: QB Josh Freeman has excelled in the two-minute offense during his career, but he knows he and the Bucs can be better.
With the offense trailing 21-17 in the end-of-the-game simulation, Freeman led the Bucs the length of the field for a score, connecting with Kevin Ogletree for a 20-yard touchdown as the receiver broke free from rookie CB Johnthan Banks and eluded S Keith Tandy.
In the next series, with 49 seconds left and the score 23-23, rookie QB Mike Glennon was intercepted by S Sean Baker.
Freeman said the Bucs have been getting good work against their defense in two-minute situations.
"Our defense does an awesome job of mixing it up," Freeman said.
"On offense, we just have to stick to our rules. The O-line has done an awesome job in those periods. It's late in practice. It's hot. Guys have to push through. Hurry, hurry, hurry. And guys were able to do that."
INJURIES: FB Erik Lorig (calf), CB Myron Lewis (hamstring), TE Luke Stocker (leg) and WR Tiquan Underwood (hamstring) did not practice.
