Ryan Fitzpatrick’s grip on the Jets’ starting quarterback job all depends on his injured knee.

Coach Todd Bowles announced Monday that Fitzpatrick is “day to day” because of a sprained left knee and that his status for New York’s game Sunday against the Rams is uncertain.

“We’ll know more as the week progresses,” Bowles said during a conference call.

Fitzpatrick injured his knee during the third quarter of the Jets’ 27-23 loss at Miami on Sunday. The quarterback left for a series and was replaced by Bryce Petty, but he returned and finished the game while wearing a brace on the knee. Though the injury is not believed to be serious, Bowles says Petty would start Sunday if Fitzpatrick is not healthy enough.

Bowles also announced that cornerback Marcus Williams has a high ankle sprain that could sideline him for multiple games.

GM’s pact extended

Atlanta General Manager Thomas Dimitroff signed a three-year contract extension Monday, ending questions about whether this season, the final year of his deal, would be his last with the Falcons.

Financial terms were not disclosed for Dimitroff’s new deal, which runs concurrently with Coach Dan Quinn’s through 2019.

The Falcons never had consecutive winning records before Dimitroff was hired in 2008, and they were above .500 in his first five seasons and made the playoffs four times. Dimitroff was credited for drafting quarterback Matt Ryan, receiver Julio Jones, running back Devonta Freeman and cornerback Desmond Trufant.

The Falcons are off to a 6-3 start this year.
