Oakland Raiders receiver Amari Cooper was a spectator at the beginning of practice Tuesday.
Cooper was in shorts and did not have his helmet while the team was in full pads. Cooper did, however, stretch with the team before position drills began. Cooper has three receptions for 27 yards this preseason, including a 20-yard catch in traffic at the Green Bay Packers last weekend. He did, however, come under scrutiny for not fully fighting for the ball on a long pass from Derek Carr against the Packers that was intercepted.
