Ta'amu, Alameda (NT)
Ta'amu has been sentenced to 18 months of probation after pleading guilty to reckless endangerment, resisting arrest and drunken driving stemming from a series of crashes and a police chase.
The Steelers released the 22-year-old draft pick a few weeks after he was arrested Oct. 14 but later re-signed him to the practice squad. Police say he crashed into several cars on the city's South Side, a neighborhood known for bars and nightclubs, then ran from officers who responded. A judge found Ta'amu not guilty Thursday of running from police after Ta'amu explained that he thought an officer in an unmarked car was an angry motorist chasing him.
Spaeth, Matt (TE)
The Steelers signed the free agent tight end on Monday, reuniting Spaeth with the club that selected him in the third round of the 2007 NFL Draft.
The 29-year-old Spaeth spent his first four seasons with the Steelers before moving on to Chicago, where he caught just 13 passes for 78 yards and three touchdowns in 31 games.
Spaeth, Matt (TE)
The Bears terminated Spaeth's contract.
Spaeth appeared in 91 games, including 56 starts, in six NFL seasons with Pittsburgh (2007-10) and Chicago (2011-12). He has 49 catches for 353 yards and eight touchdowns in his career.
Gradkowski, Bruce (QB)
Gradkowski is coming home. The Pittsburgh Steelers and the free agent quarterback have agreed to a three-year deal that will likely make Gradkowski the primary backup behind starter Ben Roethlisberger. Gradkowski's agent Rick Smith confirmed the deal through his twitter account Wednesday.
The 30-year-old Gradkowski is 6-14 in his career as a starter with Oakland, Cleveland and Tampa Bay. He spent the 2011-12 seasons with the Cincinnati Bengals, appearing in five games.
Burress, Plaxico (WR)
The Steelers re-signed Burress on Tuesday.
Burress should provide depth with the Steelers losing Mike Wallace in free agency, but he struggled to get onto the field after returning to the Steelers last November.
