Trevor Siemian will miss the remainder of the season with an ankle injury.
Siemian started Week 2 for the New York Jets with Sam Darnold out with mono.
Siemian's leg bent awkwardly when tackled by Myles Garrett. Siemian suffered torn ankle ligaments and will undergo surgery once the swelling subsides.
Luke Falk will start for the Jets until Darnold returns.
