Mark Clayton's first day of training camp began with a few friendly high-fives from teammates and a terse warning from his head coach.
"I'm going to wear your scrawny little butt out the next couple of days," Brian Billick told his first-round draft pick.
But Clayton, who held out the first five days of camp, was the one on hold yesterday. After being held out of team drills, the rookie receiver did most of his work after practice, running routes and catching passes for 20 minutes.
Then, like the chore for many rookies, he had to carry a couple of his teammates' helmets and shoulder pads off the field.
"I was ready to play today," said Clayton, as sweat rolled down his face. "Every time Coach looked back, he told me to sit back. Whenever they call my name, I'll be ready."
Billick indicated that Clayton would be allowed to participate in team drills tomorrow.
"A guy who comes late to camp, he quadruples the chance for injury because he has to catch up," Billick said. "That's where you're at risk when you let your representation take over."
A small piece of Clayton's bonus money - which totaled close to $6 million - could be gone by the time he gets to team drills.
Clayton said he will have to pick up the dinner tab for a group of 20-plus teammates, led by defensive end Terrell Suggs. And there's also the matter of his free board at quarterback Kyle Boller's house.
"He might have to start paying rent here," Boller said jokingly.
Clayton's biggest challenge now is getting his timing down with Boller.
"He's a smart guy," offensive coordinator Jim Fassel said. "He understands the game and has a feel for it. I don't think it's going to be a long process. It can't be."
J. Lewis arrives at last
Jamal Lewis reported to training camp at 1 p.m. after meeting with a probation officer in Baltimore.
After watching afternoon practice yesterday, the running back is scheduled to work on conditioning drills today. He is expected to suit up for contact drills tomorrow.
Lewis spent four months of the offseason in a federal prison and the past two in an Atlanta halfway house after pleading guilty to using a cell phone to try to set up a cocaine deal.
"I can tell he has that look in his eyes that said he's ready to play football again," said Boller, who visited Lewis two weeks ago.
Carter out two weeks
Dale Carter, who had been splitting time with Deion Sanders at nickel back, is expected to miss two weeks after suffering a deep bruise just below his knee.
"It's one of those things that Bill [Tessendorf, team trainer] tells me that I don't understand what he's saying, but he should be OK," Billick said.
The other injury issue belonged to fullback Alan Ricard, who showed up in pads before Billick told him not to practice. Ricard's knee had limited him in offseason workouts.
"That position takes a lot of pounding," Billick said. "I'd rather have him do some aggressive rehab. We'll crank him back up Wednesday."
Anderson starts with fall
The biggest obstacles that third-string quarterback Derek Anderson has to overcome are his own feet, according to quarterbacks coach Rick Neuheisel.
Anderson, the No. 3 quarterback, fell in Saturday's scrimmage against the Washington Redskins due in part to faulty footwork.
"I know it was not the way he anticipated starting his NFL career," Neuheisel said. "He's just got to become comfortable and trust his feet. We're working on that."
Ex-Terp Kelley 'sore'
After four injury-filled years at the University of Maryland - which included two torn anterior cruciate ligaments - Chris Kelley is working hard to make an impression at strong safety. Kelley said all of the injuries that have bothered him are gone.
"I'm sore, but it's just training-camp sore," Kelley said.
The Ravens experienced bad weather for the first time this camp. It rained for most of the afternoon practice, which ended a half-hour early. ...
Defensive tackle Kelly Gregg returned to practice but had a protective cover on his hyper-extended elbow. He split team drills with Aubrayo Franklin. "Every time [Franklin] shows up, he continues to get better," Billick said. Return specialist B.J. Sams (hamstring) was also back practicing. ... The Ravens signed receiver Ronald Bellamy, safety B.J. Ward and defensive tackle Tron LaFavor. Receiver Tommy Manus (Morgan State) was injury-waived.
