Frazier (6-5, 234) originally signed as an undrafted free agent and made the active 53-man roster coming out of last year's camp. After spending five days on the team's practice squad, he was signed back to the 53-man roster until he was placed on the Reserve/Injured List on Jan. 24, 2006, with an injured right leg.
Frazier played in 11 games as a rookie and posted two tackles, including one sack in the season opener against the Tennessee Titans. He also added eight special teams' tackles in the regular season.
Morgan (6-1, 215) was acquired by the Pittsburgh Steelers as a free agent on Sept. 6, 2005, after spending the 2004 season with the Dallas Cowboys. He was originally drafted by the Cleveland Browns in the second round (33rd overall) of the 2001 NFL Draft before being traded to the Cowboys on Oct. 19, 2004.
Morgan played in all 16 games in 2005 for Pittsburgh as a wide receiver and kick returner. He posted nine catches for 150 yards and two touchdowns as a receiver while returning 23 kickoffs for 583 yards (25.3 avg.), which ranked fifth in the AFC and eighth in the NFL. Morgan missed the final three postseason games after suffering a right ankle injury in the Wild Card Game at Cincinnati.
All NFL teams may sign up to eight rookies or first-year players to their practice squad after noon on Sunday, Sept. 3.
