Tennessee defensive end Derek Barnett, considered a first-round pick in next month's NFL draft, is sick and will not participate in drills at the Indianapolis scouting combine on Saturday, according to a source.
Barnett may have "caught a virus and is throwing up, has chills, etc.," the source said.
Barnett visited with the NFL combine doctor who recommended he rest Saturday, according to the source, who is hoping Barnett improves enough to work out on Sunday.
Barnett had at least 10 sacks in all three of his seasons at Tennessee.
