NEW YORK — The New York Jets will try to turn around their season without Zach Wilson for a few games.

The rookie quarterback has a sprained posterior cruciate ligament in his right knee and will be sidelined two to four weeks, coach Robert Saleh confirmed after Wilson had an MRI on Monday.

To help fill in for Wilson, the Jets acquired veteran Joe Flacco from Philadelphia for a conditional sixth-round draft pick. The pick can become a fifth-rounder based on playing time for Flacco.

Flacco started four games for the Jets last season when Sam Darnold was injured. The 36-year-old QB, a Super Bowl MVP nine years ago with the Baltimore Ravens, signed with Philadelphia in the offseason.

Wilson was injured in the second quarter of New York’s 54-13 loss to New England on Sunday.
