New York Jets quarterback Ryan Fitzpatrick has a sprained MCL in his left knee and is day-to-day, head coach Todd Bowles said Monday.
If Fitzpatrick is unable to play Sunday against the Rams, Bryce Petty would start in his place.
The injury temporarily forced him out of Sunday's 27-23 loss to the Miami Dolphins.
Fitzpatrick left the game in the third quarter after Dolphins defensive tackle Jordan Phillips rolled into his left leg. Before the next snap, he took a knee and left the game for the remainder of the drive.
Petty came in and went 2-for-2 for 19 yards, leading the Jets to a field goal before Fitzpatrick returned.
Fitzpatrick wore an ice pack around his left knee during his postgame press conference, and head coach Todd Bowles said Fitzpatrick would remain the team's starting quarterback if he stays healthy.
Fitzpatrick threw for 193 yards on 17-of-28 passing with one touchdown and two interceptions. Fitzpatrick has thrown for 1,982 yards with eight touchdowns and 13 interceptions this season.
Regardless of what you think of Fitzpatrick running this team in the weeks ahead, an MCL injury is probably the least serious injury to the knee that he could have suffered. Often times in the NFL when you just see the bland "knee injury" designation it is likely of the MCL variety.
While timeframes vary on how long it takes to recover, MCL injuries can last from zero to four weeks on average with most landing in the one to two game absence area. Since Fitzpatrick came back into the game we can assume that barring any setbacks he will be the starter for the Jets going forward, as Todd Bowles said.
Still, how he plays and the extent of his injury might lead the Jets to give Fitzpatrick a very short leash in the coming weeks. Sooner or later the Jets are going to want to see what they have (or don't) in Bryce Petty and Christian Hackenberg.
