It's a huge loss for the Jags and QB Trevor Lawrence. Jones looks like he'll be the WR1 going forward. Shenault has had mixed results with Chark out of the lineup so far. Agnew and Austin will look to battle for WR3 snaps, which could have significance as the Jags are expected to play from behind a lot the rest of the season.
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.
Laquon Treadwell has been among the Jaguars' most-consistent wide receivers thus far in camp. Every day walking off the practice field there has been talk of a Treadwell catch or touchdown that got fans and his teammates cheering.
Treadwell, a first-round selection by the Minnesota Vikings in the 2016 NFL Draft, had a standout collegiate career at the University of Mississippi – but was not as productive as he wanted in four seasons in Minnesota and last season with the Atlanta Falcons. At best, he could end up as the team's WR4 heading into the season, which means he'd be a possible injury away from significant time. It will need more time to sort itself out, but Treadwell is perhaps a name to keep in mind.
