At the time of his departure, Martin had 23 yards on seven rushes, but the Buccaneers' offense hadn't yet found its rhythm against one of the most threatening defenses in the NFC, and it never did.
Martin signed a five-year deal with the Bucs in March after enjoying a return to his freshman form last year.
Martin didn't play a pivotal role in Tampa Bay's Week 1 win over the Falcons, earning 23 touches for 96 total yards and zero touchdowns. But against the Cards, Martin would have been used frequently had he stayed in the game. Without him, Winston forced desperate throws, tossing four picks on the day, and the run game never recovered.
