And the Carolina Panthers' coaching staff tried to keep the team together after an ugly incident involving two of the team's highest-paid players.
A subdued, apologetic Smith returned to practice Monday, three days after the three-time Pro Bowl receiver punched Lucas in the face at practice, and two days after he was suspended without pay for the first two regular-season games.
"I'm completely wrong," Smith said. "It was an asinine decision. And I'll move forward better than I probably have ever had to. It's the first time in my life that I really haven't forgiven myself."
Lucas also appeared on the field for the first time since Smith slugged him while he was on one knee and not wearing a helmet.
The starting cornerback rode a stationary bike while the team worked out, thanks to the broken nose that will sideline him two to three weeks.
STEELERS: Four-time Pro Bowl nose tackle Casey Hampton remained on the sidelines as Pittsburgh began its second week of training camp.
He reported to camp July 27 far above the weight preferred by coach Mike Tomlin, and until Hampton gets into better shape, he won't practice.
CHIEFS: Rookie defensive tackle Glenn Dorsey should miss about a week after spraining his left knee in practice over the weekend.
An MRI exam showed no additional damage, the team said Monday.
EAGLES: Guard Shawn Andrews says he is battling depression and might end his training camp holdout this week.
Andrews told the Philadelphia Daily News in an exclusive interview that he has decided to get professional help and is on medication. Andrews said he is to meet a doctor Thursday and could return to the team this weekend.
DOLPHINS: Josh McCown is listed as Miami's No. 1 quarterback, for now.
Miami released its first depth chart of the season per NFL policy, putting the seven-year veteran at the top.
But coach Tony Sparano was quick to point out that second-year man John Beck and rookie Chad Henne haven't been ruled to start at quarterback for Miami's preseason opener against Tampa Bay on Saturday night.
TEXANS: Backup running back Chris Brown returned to practice after sitting out last week with a sore back.
BILLS: Linebacker Alvin Bowen is scheduled for surgery next week on a torn right knee ligament, likely ending his rookie season before it starts.
REDSKINS: Rookie receiver Malcolm Kelly had arthroscopic surgery on his left knee and is expected to be sidelined for two more weeks.
SEAHAWKS: Offensive lineman Chris Gray has retired on the eve of his 16th NFL season because of a lower back and spine injury that threatened his ability to walk.
Gray is Seattle's record-holder for consecutive games played at 121.
PATRIOTS: Signed veteran right guard John Welbourn , who started every game last season for Kansas City.
COURTS: In Tampa, Fla., domestic violence charges against Detroit Lions safety Kalvin Pearson have been dropped, the Hillsborough County state attorney's office said Monday.
