Receiver Cooper looks to fix errors

Wide receiver Amari Cooper, as he does most weeks, stood in front of his locker Wednesday and softly answered questions from reporters.

Cooper knew his six dropped passes in three games this season would be a prominent topic. They were, and he didn’t duck those questions.

“I try to move forward,” Cooper said. “Obviously, I look back on them to see how I dropped the ball, and then fix it. … Most of the balls I’ve dropped have been a result of trying to run before I actually catch the ball.

“It’s a little frustrating, but you just have to fix it.”

Cooper will try to correct this problem Sunday in Denver, against a stout defense. The Broncos rank fourth in the NFL in total defense, allowing 263 yards per game.

They also have two Pro Bowl cornerbacks in Aqib Talib (a four-time selection) and Chris Harris Jr. (three times).

“They’re probably the best secondary we’ll face this year,” Cooper said. “They have two All-Pro cornerbacks, and they take risks and make interceptions.” Injury report: Raiders cornerback Gareon Conley missed Wednesday’s practice because of his lingering shin injury. Conley made a strong NFL debut Sept. 17 against the Jets and then played more sparingly in Sunday night’s loss at Washington.

Wide receiver Michael Crabtree (chest contusion) was a limited participant in practice, as were Cooper (knee), running back Jalen Richard (calf ) and defensive back Keith McGill (foot). Briefly: Quarterback Derek Carr, asked about nationalanthem protests throughout the NFL, hinted at his next career when he said, “I’m not a politician, at least yet, so I don’t even pay attention.” Oakland players have not discussed their plans for Sunday’s anthem in Denver, according to Carr. … Former Raiders head coach John Madden will be featured in “John Madden: A Football Life,” premiering at 6 p.m. Friday on NFL Network.
