Smith (knee) is believed to have suffered a torn ACL, NFL.com's Ian Rapoport reports.

EDGE Analysis

Smith was initially thought to have avoided a serious injury, but the initial results of Monday's MRI are believed to suggest otherwise. To pin down a definitive diagnosis, Smith will visit Dr. James Andrew on Tuesday, ESPN's Adam Schefter reports. If his torn ACL is confirmed, Smith would miss the remainder of this season, paving the way for Ryan Fitzpatrick to reclaim the Jets' starting quarterback job.
