Kouandjio signed a deal with the Broncos' 53-man roster Tuesday, Mike Klis of 9News Denver reports.
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.
