"The Miami Dolphins and Richie Incognito have agreed to maintain his suspension during the ongoing NFL investigation," the team said in a brief statement.
Incognito was suspended Nov. 3 in wake of accusations of harassment, intimidation and bullying by teammate Jonathan Martin.
NFL special investigator Ted Wells is still conducting an inquiry into the club's workplace conduct as a result.
Under the terms of the NFL's collective bargaining agreement, a player can only be suspended for a total of four games, but the Dolphins' statement indicated Incognito is not choosing not to fight his continued suspension.
Martin left the team prior to a Oct. 31 game against Cincinnati.
Incognito has denied bullying Martin but has admitted using harsh and racist language.
