Quinn, who figures to compete for the starting job with Charlie Frye and Derek Anderson, has missed six practices so far.
Browns general manager Phil Savage has been in negotiations with Quinn's agent, Tom Condon, but the team said there was nothing new to report. Savage characterized talks with Condon as "in the same neighborhood, but not on the same street."
Seattle 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.
Meanwhile, offensive lineman Floyd 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.
New England defensive back Chad Scott will miss the upcoming season because of a knee injury, the team announced Monday, as cornerback Asante Samuel's holdout continued.
Scott, 32, was placed on the reserve/injured list. The news came just hours after coach Bill Belichick continued to describe Scott's injury as day-to-day.
Last season, Scott played in 14 regular season games with nine starts. He made 44 tackles and had two interceptions. He signed with the Patriots before the 2005 season, which was cut short by a shoulder injury that October.
Meanwhile, Samuel continues holding out for a multiyear agreement after rejecting a one-year, $7.79 million contract.
The linebacker's agent, Michael Huyghue, told The Associated Press the Panthers initially offered a contract with the option bonus, only to yank it off the table 24 hours later.
General manager Marty Hurney, who said Friday the two sides were "miles apart," declined Monday to answer questions about the impasse.
Beason's holdout has left the Panthers thin at linebacker. Things got worse Monday morning when Na'il Diggs, who Beason was expected to replace at outside linebacker, was carted off the field with an apparent right hamstring injury.
"I don't want the negative media attention. I don't want to be the focal point," Beason, the 25th pick in the draft, told the AP in his first interview since starting his holdout. "Already having the pressure of being the first-round pick, not having the luxury of being out there, it's hurting myself."
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.
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.
Three days into training camp, the Dolphins' offensive line jobs are completely up for grabs. The team is experimenting with different combinations, searching for the best lineup.
"We're a long way from, in terms of our offensive line, making any decisions on who starters will be and what the starting unit will be," coach Cam Cameron said. "There will be some different combinations working through throughout training camp. Every day is an evaluation process."
During Monday morning's practice, the first-team offensive line was Vernon Carey (left tackle), free-agent acquisition Chris Liwienski (left guard), second-round draft pick Samson Satele (center), sixth-round pick Drew Mormino (right guard) and third-year veteran Anthony Alabi (right tackle).
Indianapolis placed former Pro Bowl safety Bob Sanders and linebacker Keith O'Neil, a key special teams performer, on the physically unable to perform list.
Neither was expected to practice at the start of training camp after having offseason medical procedures. Sanders had shoulder surgery, while O'Neil underwent sports hernia surgery.
Tarik Glenn, who announced his retirement last week with one year left on his contract, was placed on the reserve/retired list.
Defensive tackle Quinn Pitcock, a third-round choice out of Ohio State, was placed on the reserve/drafted-unsigned list because he has not yet passed his physical.
Four-time Pro Bowl LT 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 hurt when another player feel 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.
Green Bay coach Mike McCarthy said Monday that the knee injury sustained by projected starting running back 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.
McCarthy said Morency probably won't need arthroscopic surgery.
While Jackson is bound to draw attention as a high draft pick, McCarthy has been impressed with returning veteran Noah Herron.
Gore was injured during a non-contact ball-handling drill, and coach Mike Nolan said he would not practice with the team for the remainder of the week. Gore will be re-evaluated next Monday, and Nolan expects him to return to practice then with a cast on his hand.
Eleven-time Pro Bowl guard Larry Allen reported for training camp after missing Saturday's reporting date and Sunday's first practices due to personal reasons.
Allen was a stranger to the team facility during the offseason and was a no-show for the 49ers' May mini-camp and June organized team activities. Rumors circulated that he was considering retirement, but Allen said he has no intention this year to end a career that has established him as one of the greatest offensive linemen in NFL history.
