NFL Commissioner Roger Goodell said Monday that the league is looking to "find out all the facts" regarding the allegations and that once the investigation is finished, "we'll determine what the next step is from there, if any."
The NFL is trying to determine whether the three-time MVP violated its personal conduct policy. Should the league find he did, Favre could be fined or suspended.
TRADE: Deion Branch , the former Super Bowl MVP wide receiver with the Patriots, was traded Monday night from the Seattle Seahawks to New England. The trade ended a day of speculation after Branch was absent from Seahawks practice.
PACKERS: Quarterback Aaron Rodgers suffered a concussion Sunday and might have to sit out this weekend's game against Miami. The backup quarterback is Matt Flynn , a third-year player out of Louisiana State who has thrown 17 passes in his career.
PATRIOTS: Coach Bill Belichick downplayed a report that Randy Moss and Tom Brady had an altercation before the wide receiver was traded to the Minnesota Vikings last Wednesday.
"That's news to me," Belichick said during a conference call.
CBS studio analyst Charley Casserly reported that the week before the trade, Brady and Moss "went-toe-to-toe and had to be separated."
"One of Brady's problems with Moss was his behavior as a Patriot," Casserly said. "Then one of the things that was overheard was Brady telling Moss, 'You need to cut your beard.' Moss counters, 'You need to get your hair cut. You look like a girl.' "
49ERS: Quarterback Alex Smith is keeping his starting job for at least another week. Coach Mike Singletary said he plans to evaluate Smith's status on a week-to-week basis from now on.
RAMS: Leading receiver Mark Clayton will have season-ending surgery on his right knee to repair a torn patellar tendon and is done for the year.
BRONCOS: Denver will be without five key players, including three members of its secondary, when the New York Jets visit Invesco Field next weekend.
Coach Josh McDaniels already has ruled out safeties Brian Dawkins (knee) and Darcel McBath (ankle) and cornerback Andre' Goodman (thigh) along with pass-rusher Robert Ayers (leg) and special teams captain Wesley Woodyard (hamstring).
The Broncos declined to comment on a Denver Post report that Ayers would miss as many as three months with a broken foot.
PANTHERS: Coach John Fox said it's "too early to say" whether rookie Jimmy Clausen will remain the starting quarterback for winless Carolina. But Fox rejected talk of making changes to his staff.
BROWNS: With quarterbacks Jake Delhomme and Seneca Wallace both nursing severe ankle injuries, Browns coach Eric Mangini said it's possible that rookie Colt McCoy will make his regular-season debut Sunday against the Pittsburgh Steelers.
BILLS: Calling himself "a realist," owner Ralph Wilson warned that it might take as many as three years to rebuild his 0-5 team and said drafting a quarterback next year is the club's top priority.
