ESPN NFL Training Camp 2007

Minnesota Vikings: Adrian Peterson was all smiles during his first day of training camp with the Vikings.

Peterson reported to camp on Monday after a three-day holdout ended with him signing a five-year, $40.5 million contract late Sunday night. He arrived in Mankato around 11 p.m. and immediately went to work trying to make up for the five practices he missed.

"I was excited," Peterson said. "I'd be lying if I said I didn't have any butterflies at all. That's all part of it. But once I got out there I got comfortable and got loose and it was all having fun again."

The Vikings have said his collarbone -- which was broken twice last year at Oklahoma, including in the Sooners' Fiesta Bowl loss to Boise State in January -- is fine and he is cleared for full practice.

Peterson participated in the full-pad session in the morning, absorbing a few hits, but he sat out the live 11-on-11 drill toward the end of practice.

"It's like starting over again," Peterson said. "It feels good to be out here and just have everything behind me, the collarbone, to have that behind me and over and done with, so it just feels good."

Childress said Peterson showed the fresh legs of someone who hasn't dragged through five practices in the heat.

"He showed some of that explosion that we anticipated and, by in large, did a good job," Childress said.

Elsewhere in NFC camps:

Seattle Seahawks: Seahawks safety Jordan Babineaux will miss the next three to four weeks of training camp after injuring his right knee on the first day of practice.

Babineaux got tangled with wide receiver Ben Obomanu while leaping for a pass in the morning practice Sunday and then banged his right knee while skidding across the wet grass.

Coach Mike Holmgren said Monday that a scan on Babineaux's knee showed a bone bruise, and the player teammates call "Big Play Babs" wouldn't miss significant time.

"He has the bone bruise and the feeling is that we'll have him back in three or four weeks. That was good," Holmgren said.

Meanwhile, oft-injured offensive lineman Floyd "Pork Chop" Womack again injured his hamstring. Womack has been hampered by leg injuries in recent seasons and was being limited in practice following double knee surgeries in the spring.

Tampa Bay Buccaneers: Buccaneers general manager Bruce Allen disputed a published report Monday that quarterback Chris Simms has a sore arm and may wind up being placed on injured reserve.

Simms had surgery last September to remove his spleen and has struggled to regain his passing touch. He's competing in training camp with two other quarterbacks for the backup job behind starter Jeff Garcia.

The St. Petersburg Times reported on its Web site Monday that the 26-year-old quarterback, who's been limited in practice the past two days, may be a candidate for injured reserve.

"Chris, as all quarterbacks who go through training camp, deal with different soreness," Allen said. "We have some defensive linemen who have sore elbows, sore shoulders from pounding. Nothing unusual. I saw the report, headline and all that. That's inaccurate."

Simms and coach Jon Gruden were not available for comment after the Bucs canceled a special teams practice because of an afternoon thunderstorm. The quarterback did participate in a morning session.

Green Bay Packers: The Packers went into training camp looking a little bit shaky at running back. Now they're banged up, too.

Packers coach Mike McCarthy said Monday that the knee injury sustained by projected starter Vernand Morency was worse than the team's medical staff originally thought, and that he now expects Morency to be out "a couple" of weeks.

The good news: McCarthy said Morency probably won't need arthroscopic surgery.

"I don't think so, no," McCarthy said. "[Team doctor] Pat McKenzie just thinks it's a little more serious than he initially thought. Just like I said, it's going to be maybe a couple weeks."

Morency injured his knee in the Packers' first training camp practice on Saturday. He wandered the sidelines without pads in the Monday afternoon heat.

Washington Redskins: Four-time Pro Bowl left tackle Chris Samuels could miss all of the preseason games after hurting his right knee during the afternoon practice. An MRI revealed an isolated grade 2 sprain of the MCL, which will sideline him up to four weeks.

Samuels was injured when another player fell on the leg during a play-action pass, and the surrounding players reacted with a collective "oooooh" as he went down.

"I thought it was over with for the season," said Samuels, who sprained the same knee in 2003.

Also, tight end Pete Schmitt hurt the rotator cuff in his left shoulder and was also scheduled for an MRI. Wide receiver Mike Espy (bruised knee), linebacker Dallas Sartz (strained hamstring), guard Randy Thomas (sore knee) and linebacker Marcus Washington (sore hip) missed practice.

Detroit Lions: Lions rookie quarterback Drew Stanton will have arthroscopic surgery to clean cartilage from his right knee, and could be out as long as a month.

Stanton, a second-round draft pick out of Michigan State, tweaked the knee during training camp workouts Sunday and has not taken part in drills since. The team hopes to schedule a date for the procedure soon.

Team president Matt Millen said Monday the problem is not related to an injury Stanton sustained to the same knee during the 2003 Alamo Bowl. That required offseason surgery and dogged Stanton during the 2004 season.

Stanton, expected to be the third quarterback this season behind starter Jon Kitna and either Dan Orlovsky or J.T. O'Sullivan, will remain on the active roster while he recovers from the procedure.
