The FBI is opening an internal investigation into the fight between Chicago Bears offensive linemen Olin Kreutz and Fred Miller at its shooting range in the Chicago area, special agent Richard Kolko said yesterday.

Miller, who initially said the injury occurred in a fall at home, needed surgery after Kreutz broke his jaw in the altercation last week.

An FBI official said several Bears players were invited to take target practice. The official, who spoke on condition of anonymity because of the internal investigation, said it is common for FBI field offices to invite community groups to shooting ranges.

The official said the fight took place after the shooting session, during a barbecue for FBI employees and the players. He confirmed that alcohol was consumed during the barbecue, but said there was no drinking during the target practice.

Reports of an altercation surfaced after last Sunday's 17-9 victory over San Francisco, and details have continued to leak.

The Chicago Sun-Times, citing sources, reported roughhousing between Miller and Kreutz escalated to a full-blown altercation. As he was being escorted out the door, Miller turned around and went toward Kreutz, the newspaper reported. Kreutz then hit him in the face and Miller responded by striking Kreutz in the head with a five-pound weight, opening a cut that required 13 stitches, the newspaper reported.

Coach Lovie Smith told reporters on Monday he was not aware of the incident until last weekend. He also said then that neither player would be suspended, but intimated they would be fined. It was not clear if the Bears had taken disciplinary action as of yesterday.

* EAGLES: Donovan McNabb will miss Sunday's against the Giants because of a groin injury. Mike McMahon, who had been the third-string quarterback, will get the start over backup Koy Detmer.

McNabb's status beyond this week is uncertain. He'll see a specialist today. McNabb has played through several injuries this season, including a sports hernia that will require surgery.

* SUPER BOWL: NFL owners voted to tentatively award Kansas City a Super Bowl, largely as a tribute to owner Lamar Hunt, who gave the game its name.

It comes with one giant string attached: improvements to Arrowhead Stadium, including a retractable roof to keep out the February cold. The team estimates the cost of the roof alone at $100 million to $200 million -- and that's not counting $300 million or so the Chiefs say they need in stadium upgrades.

The approval is for a 10-year window, starting in 2011, but Hunt said the most likely prospects would be for the 49th or 51st Super Bowl, after the 2014 or 2016 seasons.

* RAVENS: Safety Ed Reed and linebacker Ray Lewis, the past two NFL defensive players of the year, have been ruled out of Baltimore's game against the Pittsburgh Steelers on Sunday. Reed has not played since spraining his ankle on Oct. 16; Lewis has missed the past three games with a thigh injury.

The Ravens (2-7) were hopeful that Reed would be able to resume practicing this week. He was in team meetings yesterday but did not practice. Reed said that he is "day-to-day." Guard Keydrick Vincent (thigh) has also been ruled out. Brian Rimpf, a seventh-round draft pick in 2004, will start in his place.

* FALCONS: Wide receiver Roddy White skipped practice after being involved in an auto accident. The vehicle was damaged but White wasn't seriously injured, Coach Jim Mora said. No other vehicle was involved in the crash.

* BILLS: Quarterback Kelly Holcomb missed practice, still recovering from the aftereffects of a concussion. J.P. Losman might start Sunday at San Diego.

* RAMS: Guard Tom Nutten, who nearly retired last year because of injuries, is out for the season with a neck injury.

* VIKINGS: Running back Moe Williams will miss the remainder of the season following surgery on his right knee.

* DOCTOR INDICTED: A doctor accused in a television report of writing illegal steroid prescriptions for three former Carolina Panthers has been indicted on 14 additional charges. A federal grand jury added three counts of distributing anabolic steroids and 11 counts of distributing human growth hormone to the 29 other similar counts against James Shortt.
