Jaguars head coach Urban Meyer said Wednesday that Jones is dealing with an AC joint sprain in his shoulder, John Reid of The Florida Times-Union reports.
The wideout's status now will need to be monitored as Jacksonville's Sept. 12 season opener in Houston approaches. Once Jones takes the field in the regular season, he'll be catching passes from No. 1 overall pick Trevor Lawrence, who was confirmed as the Jaguars' starting quarterback Wednesday.
