Amerson got starter’s playing time Sunday at Chicago after playing significantly in Week 3, just days after being claimed off waivers from Washington. Amerson, a second-round pick in 2013, played extensively as a rookie with the Redskins, but his playing time had decreased.
“He’s really picked up the system well,” Del Rio said. “He’s done a nice job coming in here and showing some of the skill that we thought he would have, and he’s added to the group. He’s been a good contributor. He forced a nice turnover yesterday. He’s had some sticky coverage, and we think he’s got a chance to help us.”
In other Raiders' notes:
Del Rio did not have an injury update on safety TJ Carrie, who left Sunday's game in the second quarter after taking a hit on a punt return. The team announced that he had a chest injury. Carrie's arm was in a sling after the game. With Taiwan Jones dealing with a foot injury, both of Oakland’s returners are banged up.
Del Rio praised the play of defensive end Aldon Smith. Smith had his first sack as a Raider and he was dominant against the run. Del Rio said Smith has improved in each of the four games he’s played with Oakland.
