No, this isn't a joke:
Coach Gase announces QB Sam Darnold will miss Monday night's game with mono. https://t.co/R5KBJtTiVA— #TakeFlight (@nyjets) September 12, 2019
Trevor Siemian will start on Monday night and probably the following Sunday against New England as well. Luke Falk is to be elevated from the practice squad to back him up.
It's fair to say the last week couldn't have gone much worse for the Jets, for whom Le'Veon Bell, CJ Mosley, Quinnen Williams and Demaryius Thomas all missed practice.
More on this to follow...
