PHILADELPHIA (AP) - Philadelphia's top prosecutor says he won't rush his decision on whether to charge Buffalo Bills running back LeSean McCoy over a nightclub fight.

District Attorney Seth Williams is feeling heat from the city's police union because two off-duty officers were injured in the Feb. 7 brawl.

But Williams on Friday says his goal "is to get it right, not get it fast."

Investigators say the 3 a.m. fight erupted over which group had purchased a $350 bottle of champagne at the after-hours club. One officer suffered a broken nose and broken ribs while a second had a possible skull fracture.

Defense lawyer Dennis Cogan says McCoy was sober and did nothing wrong.

The 27-year-old McCoy spent six years with the Philadelphia Eagles before playing for Buffalo last season.
