Arizona Cardinals running back Marcel Shipp, the team's leading rusher last season, will miss at least eight weeks with a broken left leg.

Cardinals Coach Dennis Green said Shipp appeared to have dislocated his left ankle in the team's intrasquad scrimmage on Friday, but more X-rays revealed a broken fibula.

"We were hoping that would not be the case, but it looks like it probably will be," Green said yesterday in Flagstaff, Ariz.

A team official said that Shipp will have a plate and screws inserted into the injured leg in a few days to stabilize the fracture, and additional surgery to add pins is expected.

Shipp, who led the Cardinals with 830 rushing yards in 2003, was caught beneath a pile during a routine running play and had to be helped off the field on a cart. He was unavailable for comment yesterday.

Damien Anderson and Josh Scobey will now battle it out for the No. 2 spot on the depth chart behind starting running back Emmitt Smith.

* BILLS: Four touchdowns, one big stiff-arm and a standing ovation: Not bad for Willis McGahee's first time competing in an NFL setting.

"Today was a good day," the Bills running back said after a scrimmage against the Browns in Pittsford, N.Y. "I was a little nervous on the first series, but after the second series, when I kind of got into a rhythm, everything went good for me."

Selected 23rd overall in the 2003 draft, the former University of Miami star missed all of last season recovering from reconstructive surgery on his left knee, which he hurt in the national championship game against Ohio State earlier that year.

He experienced his first full-contact session in training camp earlier this week, and the scrimmage yesterday was McGahee's first time lining up against an opponent since he was hurt.

"That was good to see," Bills Coach Mike Mularkey said. "It's your first time in live-action since that infamous game, so I think the rust is coming off slowly but surely."

* BROWNS: Linebacker Brant Boyer will miss at least eight weeks after undergoing surgery to repair a broken bone in his right foot.

Boyer, a 10-year veteran and the Browns' special-teams captain, was hurt Friday when someone stepped on his foot during the first of two practices between the teams.

Bills' Willis McGahee, who missed all of last season after reconstructive surgery on his left knee, runs for 4 touchdowns in scrimmage vs. Browns.
