The Colts can void running back Trent Richardson's $3.18 million guaranteed salary for 2015 because he was suspended for conduct detrimental to the team, reports CBS Sports' Joel Corry, a former agent who's an expert on player contracts.

Richardson, who missed a walkthrough before the AFC title game, received a two-game suspension from the team, general manager Ryan Grigson confirmed. If Indy chooses to keep Richardson, he'd serve the second game of the suspension next season.

ESPN.com expects the Colts to exercise their option to void Richardson's contract, and the players' union to challenge that move.
