Treadwell caught one of three targets for 11 yards during Sunday's 30-10 loss to San Francisco.
Treadwell finished second among Jacksonville's wideouts with 29 offensive snaps in the blowout defeat and also tied for third on the team in targets. Jamal Agnew (hip) now is on injured reserve and set to miss the rest of the season, leaving Treadwell and Tavon Austin to compete for reps as the Jags' No. 3 wide receiver behind Marvin Jones and Laviska Shenault.
