A federal judge has blocked the National

Football League from suspending five players for violating the

league's anti-doping policy.

U.S. District Judge Paul Magnuson said Friday he needed more

time to consider the case after hearing several hours of arguments

from the league and the NFL Players' Association.

Kevin Williams and Pat Williams of the Minnesota Vikings and

Charles Grant, Deuce McAllister and Will Smith of the New Orleans

Saints all were suspended this week for four games. They tested

positive for a banned diuretic in a dietary supplement called

StarCaps.

The union has argued that the NFL didn't properly inform players

about the substance. The NFL's attorneys argued that that claim,

and others, had been considered and rejected in a process set out

by the league's collective bargaining agreement.
