Petty will start the final four games for the 3-9 Jets, beginning with Sunday's trip to San Francisco.
Fitzpatrick was benched once already, after the Jets started 1-5. He was benched again at halftime of Monday night's 41-10 loss to the Colts. Fitzpatrick threw an interception and had a 30.2 quarterback rating in the first half. Petty has some talent to work with at WR and RB but it remains to be seen how much of a spark he can provide so he'll be a risky fantasy option.
