The Raiders announced they've signed running back Trent Richardson, who was cut by the Colts last week after two disappointing seasons with the team.
The deal is set to pay Richardson $3.9 million over two years but includes incentives that can raise the deal to $4 million per year, NFL.com reports.
Richardson joins a backfield featuring Latavius Murray, Roy Helu and Marcel Reece. Richardson has averaged 3.3 yards per carry over his career since being drafted No. 3 overall in 2012 by Cleveland.
Richardson scored 12 touchdowns as a rookie but has a total of seven in the past two seasons.
