Raiders quarterback Derek Carr was absent from the first full-team practice during OTAs on Tuesday due to an undisclosed injury, according to the Associated Press.

Coach Jack Del Rio did not further comment on Carr's status since he said it is not in his policy to discuss offseason injuries. He only said Carr was one of a handful of players who could not partake in practice.

Carr started all 16 games as a rookie in 2014. He completed 58.1 percent of his passes for 3,270 yards, 21 touchdowns and 12 interceptions. He had a 76.6 quarterback rating as the Raiders went 3-13.
