S4E19 Tony's Comeback

Tony starts training with a new cab driver named Lucius, who happens to be a former football player. Thanks to Lucius, Tony gets into phenomenal shape and feels motivated to pursue the reinstatement of his boxing license. Although he doubts the boxing commission will grant his request, he’s pleasantly surprised when he gets his license back and even lands a major fight against an up-and-coming boxer. However, Lucius leaves for Miami to try out for the Dolphins, and without him, Tony loses his drive and his training falters. During the fight, Tony struggles until Lucius arrives to share his good news, reigniting Tony's spirit. With his friend's encouragement, Tony rallies and knocks out his opponent.
