The Indianapolis Colts lost cornerback Sauce Gardner for much of Week 13's loss to the Houston Texans. He hurt his calf, according to the team, on the Texans' first drive. The corner's absence didn't greatly affect the defense, however, as Indy played fairly well.
Plus, let's be honest, Gardner missing most of the game simply meant the referees didn't have a chance to call him for a penalty he didn't deserve. Kenny Moore II wasn't so lucky.
As far as how long Gardner might be out? There is no definite timeline. According to a recent report from ESPN's Jeremy Fowler, the cornerback will likely miss "a few weeks," but if that is the case, then Gardner did avoid a major injury.
