Kouandjio was cut by the Broncos on Tuesday, Ryan O'Halloran of The Denver Post reports.
The Alabama product had been used as a depth offensive linemen for the Broncos after signing with the team Nov. 20. With injuries to their secondary, Denver elected to cut Kouandjio in favor of free agent cornerback Jamar Taylor.
The 2014 second-round pick by Buffalo failed to meet expectations, and has started just seven of 27 career games. Kouandjio already started a game for Denver last season, so the familiarity with the team could be a reason he was brought back. It's unclear what sort of role the Alabama product will have with the team.
