Chark suffered a fractured ankle during Thursay's matchup against the Bengals, Ian Rapoport of NFL Network reports.
Chark is out indefinitely. This is a significant injury for the Jaguars, who have struggled to an 0-3 start before Thursday's game. Marvin Jones and Laviska Shenault should be considered the main beneficiaries of Chark's absence, while Tyron Johnson and Tavon Austin can replace some of the speed that Chark offers.
