ALAMEDA — Amari Cooper”s upcoming matchup with New York Jets standout cornerback Darrelle Revis is built for headlines, not that Cooper is one to offer much on the topic.

“It”s going to be a tough matchup,” said Cooper, the soft-spoken Raiders” first-round pick who has needed all of six games to establish himself as one of the best young wide receivers in the league.

What are Cooper”s thoughts on Revis, the six-time Pro Bowler generally considered among the NFL”s top couple of cornerbacks?

“He”s definitely at the top of the league,” Cooper said.

And what makes him so good?

“He”s just really sound.”

For all his flashy play — Cooper leads the league with 302 yards after the catch, per Pro Football Focus — the former Alabama star isn”t one for feeding the hype machine. But his early numbers are eye-popping.

The No. 4 overall pick is tied for the team lead with Michael Crabtree at 33 receptions and leads the team with 519 receiving yards. He”s on pace to catch 88 passes for 1,384 yards and eight touchdowns.

Cooper”s already the first rookie with three 100-yard receiving efforts in his team”s first six games since Hall of Fame tight end Mike Ditka in 1961 and just the fifth rookie to top 500 yards receiving in that time span.

Jets coach Todd Bowles said Cooper is “anything but a rookie. He runs all the routes and is explosive off the ball. He has great hands. Excellent route runner. He”s very competitive.”

Raiders general manager Reggie McKenzie picked Cooper two spots ahead of the Jets” first pick, when New York took defensive end Leonard Williams. The standout from USC is off to a good start and already rates among the better 3-4 defensive ends in the league, but the Raiders are thrilled to have taken Cooper.

“If you watch the guy play live, watch him practice, interview him, he”s a pro-mentality guy,” McKenzie said. “We hoped he would be this good, especially with the quarterback we got that we felt could get him the ball. Is he more? I don”t know. I was just excited to get him.”

Cooper finally showed a little bit of emotion after his 52-yard touchdown reception Sunday against the San Diego Chargers, breaking into a brief celebration that saw him raise his arms to the crowd. He was even caught smiling on the sidelines.

“I was just excited that I scored a touchdown,” he explained.

Quarterback Derek Carr enjoyed seeing that brief stray from his ultraserious and focused demeanor.

“It was nice for him to come out of his shell about 1 percent,” Carr said. “I think as he continues to play and continues to gain confidence — which he”s already confident — I think that he”ll open up a little more. But I don”t know about too much more. I think that”s just his personality.”

It”s that personality, Carr believes, that contributes to his on-field success. Cooper already has battled several top-notch corners — including a standout day against Cleveland”s Joe Haden that saw him catch six passes for 87 yards while being defended by the two-time Pro Bowler.

This week, Cooper has shown no indication of having an extra edge about him as he prepares to take on Revis for the first time.

“He”s always the same guy,” Carr said. “Just like we saw him walk by, quiet, just going about his business. That”s what he does. He”ll joke around here and there and all that, but you don”t see a heightened sense of urgency or anything. He”s the same guy, and I think that”s what makes him great.”

“I”ll be ready to go,” Allen said Wednesday. “I”m glad to be out there practicing right now. I”m feeling good. I”ve just got to be patient.”

Allen injured his right knee in the first quarter of the season opener, his first regular-season game with the Raiders after signing a four-year, $23 million deal this offseason.

He was placed on the designated to return injured reserve and made his formal return to practice when he participated in a walk-through on Tuesday. That began his 21-day window in which he can practice.

Allen can be activated in time for the Nov. 15 home game against the Minnesota Vikings. If he”s not activated, the team has until Nov. 17 to activate him or he must go on injured reserve for the rest of the year.

Ellis originally injured his ankle in the season opener and missed the next two games, returning Oct. 4 against the Chicago Bears. He reinjured the ankle in practice Oct. 14 and hadn”t participated since.

Autry suffered a concussion against the Bears and missed the Oct. 11 game against the Denver Broncos. He returned to practice on Oct. 21, only to be back out a day later after concussion symptoms returned.

Safety Charles Woodson took Wednesday off, as is his usual routine after his shoulder injury suffered in the opener. He”s also now listed as having a knee injury. Cornerback/safety TJ Carrie (shoulder) and cornerback Keith McGill (foot) were both limited. Neiron Ball, who is expected to miss about a month with a knee injury, also didn”t participate.
