Report: Oakland Raiders waive RB Trent Richardson

Running back Trent Richardson, who was the third overall pick in the 2012 NFL Draft, was released by the Oakland Raiders on Monday, ESPN.com reported.

This could be the end for the 25-year-old Richardson, who has not lived up to the promise he showed at Alabama.

Richardson had a disappointing rookie season with the Cleveland Browns, and he was then traded to the Indianapolis Colts for a first-round pick during the 2013 season.

He averaged just 2.9 yards per rushing attempt in 14 games for the Colts in 2013, and he rushed for 519 yards and a 3.3 average in 15 games for the Colts last season.

Richardson clashed with Colts leadership and was cut in the offseason. The Raiders picked him up, but he did little in the preseason.

Pro Football Talk reported the Raiders also waived wide receiver Kenbrell Thompkins, who caught 15 passes for 209 yards in 12 games (six starts) last season after being acquired from the New England Patriots.
