The Houston Texans' defense took a major blow Friday when defensive rookie of the year Brian Cushing learned he is being suspended four games for violating the NFL's steroid policy, according to league sources.
Cushing appealed the league's decision at a hearing at the NFL scouting combine in February but was informed Friday his appeal had been rejected, according to sources.
Cushing will be allowed to participate in training camp with the Texans this summer, but then will serve his four game suspension to start of the 2010 regular season.
Cushing's attorney, Harvey Steinberg, did not return telephone calls seeking comment.
The Texans defense will suffer without Cushing, especially considering that its first game of the season is against the defending AFC South champion Indianapolis Colts. Cushing will also miss games against the Washington Redskins, Dallas Cowboys and Oakland Raiders.
Cushing, who was voted to the Pro Bowl, had 133 tackles, helped lead the Texans to a 9-7 record, their first winning record in franchise history. Cushing finished the season with five sacks, four interceptions and two forced fumbles.
