Julio Jones is not at the Atlanta Falcons' facility Monday for the start for the team's organized team activities, a source told ESPN's Dianna Russini.
The OTAs are voluntary. The next mandatory activity is veteran minicamp, scheduled to be held June 12-14.
One source told ESPN's Vaughn McClure: "I doubt he shows up,'' as Jones is looking for a pay raise with three years and $34.45 million left on his deal.
General manager Thomas Dimitroff said late last month that the team is not overly concerned about the Pro Bowl wide receiver missing offseason workouts or erasing Falcons photos from his Instagram page.
