Dolphins backup running back Sammy Morris will be suspended for the first four games of the regular season for violating the league's steroid policy, his attorney said Thursday. Morris tested positive for ephedrine on Oct. 17, 2005, the day after a 27-13 loss to the Buccaneers. Ephedrine is on the banned stimulant list of the NFL's Policy on Anabolic Steroids and Related Substances, which calls for a suspension for the first violation. The league's substance-abuse policy calls for admission into the program and counseling for first-time offenders. Morris, 29, gained a career-high 532 yards with six touchdowns in 2004 when filling in for the retired Williams. Last season, he gained 58 yards on 16 carries, and was used more as a fullback, but led the team with 16 special-team tackles.
