Trevor Siemian suffered a gruesome injury against the Browns on Monday.
The Jets quarterback, filling in for starter Sam Darnold (mononucleosis), appeared to sustain a lower leg injury in the second quarter after being hit by Myles Garrett, who was flagged for roughing the passer (his second such penalty of the game).
Siemian limped to the locker room with trainers.
Luke Falk, the Jets’ 2018 sixth-round pick and third-string QB, took over under center.
