The Jets have a big storyline to follow heading into their Thursday Night Football meeting with the Baltimore Ravens.
Quarterback Lamar Jackson, the frontrunner for the NFL's MVP honor this season, was limited in practice on Monday.
In the Ravens' recent 24-17 win over the Buffalo Bills in Week 14, Jackson apparently suffered a quad injury.
He only had 40 yards rushing in the contest, his lowest season total since only rushing for six yards in his team's season opener in a blowout of the Dolphins.
Baltimore head coach John Harbaugh confirmed the injury took place this Sunday and declined to say if Jackson would be limited in practice on Tuesday.
"It's hard to say. It's not a serious injury in that sense. This is day to day. We play Thursday night. We'll see where we're at," Harbaugh said via ESPN.
Per reports, Jackson had a bit of a limp during the Ravens' Monday walk-through practice. Baltimore's backup QB is Robert Griffin III and during media viewing, he took the few first-team reps in practice. Griffin hasn't started in the regular season since 2016.
Along with Jackson, the Ravens' receiving leader, tight end Mark Andrews (knee), and starting left tackle Ronnie Stanley (concussion) also missed practice.
