D.J. Chark (ankle) will be placed on IR on Monday, John Shipley of SI.com reports.
Chark fractured his ankle against the Bengals during Thursday night of Week 4. He'll be out for the season, leaving the Jags top targets as Jones and Shenault. QB Trevor Lawrence could look toward newly-acquired TE Arnold more as well. Johnson and Agnew are next up at the WR position.
