It wasn't a full workout because Thomas is at 90 to 95 percent of his normal capabilities while he continues to rehab the foot, and the 6-foot-3, 229-pound first-round draft prospect didn't run the 40-yard dash.
Thomas has recorded a 4.38 previously.
We're told that he capped the workout with an explosive, full-speed over-the-shoulder catch.
For the most part, the workout was a series of situational positional drills where Thomas caught passes while running pass patterns at less than full-speed.
The chance of a recurrence of the foot injury, a broken fifth metatarsal that required surgery, is considered minimal. This close to the draft, though, it wasn't considered a good idea to take an unnecessary risk.
Roughly 13 NFL teams were in attendance, including the Baltimore Ravens, Cincinnati Bengals, New York Jets, St. Louis Rams and the Cleveland Browns. Other NFL teams are going to be sent a DVD of the workout session.
The Ravens were one of Thomas' official predraft visits.
Last season, Thomas caught 46 passes for 1,154 yards and eight touchdowns while averaging 25 yards per reception.
Thomas played in a run-first offense, but caught 120 career passes for 2,339 yards and 15 touchdowns.
Thomas has an ideal size-speed combination.
Because he played in a fairly limited offense in college, Thomas will probably need some time to adjust to the entire NFL route tree.
