According to NFL Network's Ian Rapoport and Tom Pelissero, Jones is dealing with a leg issue. If he can't play Sunday, Tennessee might be missing its top two receivers.
A.J. Brown left last week's win over the Indianapolis Colts with what was later reportedly diagnosed as a hamstring strain. He is week-to-week.
Jones was acquired via offseason trade from the Atlanta Falcons. In his first three games with Tennessee, the seven-time Pro Bowler has 12 receptions for 204 yards and is still looking for his first touchdown as a Titan.
If both Jones and Brown are out on Sunday, the Titans will likely rely on Chester Rogers and Nick Westbrook Ikhine at wide receiver. Josh Reynolds, who was a healthy scratch in Week 3, could also see his role increase.
Tennessee will face the Jets at 1 p.m. ET Sunday at MetLife Stadium.
