Petty will start in the final four games of the season, Andy Vasquez of The Record reports.
Coach Todd Bowles made the proclamation at Monday night's press conference following their lopsided loss to the Colts. Petty actually relieved Ryan Fitzpatrick in the game, but threw two interceptions and only converted 11 of his 25 pass attempts for 135 yards and one touchdown. Even though Petty has been unspectacular in his previous starts this season, he will have a somewhat favorable matchup Sunday against the 49ers, a team that has held its opponents to 246.9 passing yards per game this season.
