NAPA – Antonio Brown threw up a hunting helmet and jersey on Sunday morning and went out for training. The superstar receiver ran a few stretches in a through-time, caught one or four passes from quarterback Derek Carr, and was back in the field house before the team was stretched.
The cameo was long enough to pull him off the non-quarterback. Football injury list. Brown formally maintained his physical condition and was released for training, although the Raiders intended to put him back into action.
That makes sense. There is no point in pushing Brown at this early stage if nothing is at stake for six weeks.
While Brown was technically back in training, he was hardly back in action. His active time was short before he went to his wife and sons in the VIP tent when things were in full swing. He changed from the jersey back to the jersey to finish his session on Sunday with his team.
It is uncertain when Brown's activity will increase, though it is hard to imagine that he will fully train for the first time in a cushioned session. The Raiders will do this Monday and Tuesday before taking off Wednesday. His activity could slowly increase and work at full speed.
The Raiders were not worried about a minor but unknown injury when Brown was placed on the NFI list on Friday afternoon. 1
J.J. Nelson flashes
The wide receiver signed with the Raiders in full Free Agency and was then quickly moved into the squad bubble. The former Cardinal of Arizona must fight to form a squad with Brown, Tyrell Williams, Dwayne Harris, Ryan Grant and Hunter Renfrow from the fifth round of 2019.
The lightning-fast speed of the Sprinter helps Nelson make a climb.
"That was an important reason why we signed him," Olson said. "He's one of the faster wide-angle receivers in the league, and he's still showing it like he is today." He caught a slope over the middle in an early phase, adjusted to the ball and broke up yet for a big win. A short time later, Nelson struck his man through the seam, returned to the ball and scored a nice touchdown goal on the goal line.
"The best thing about him is that he has great ball skills in catching the ball and he has a great vertical speed," Olson said. "There are things we will teach him to try to match his abilities."
Lester Hayes encourages Isaiah Johnson
Instead of letting former players participate in a second day of training, the Raiders had a wine-red evening. Tasting tour planned for her alumni on Sunday morning. Legendary cornerback Lester Hayes was perhaps the last on the bus to make this trip. He was right on the sidelines during the posture exercises, trying to help the current Raiders Cornerbacks.
Hayes was particularly struck when rookie Isaiah Johnson broke off a deep play with his left, non-dominant hand. That's exactly what Hayes encouraged defenders to work on during a speech on Saturday, and Johnson clearly listened.
More action in the field
– While Day 1 of the training camp seemed to have been offensive, defending the front row seemed much better on the second day. At the start of the individual work, Carr threw a low pass intended for Brian Burt, but the receiver was covered by Nick Nelson, who scored easily. Gareon Conley was also good at individual practice and was able to split three runs before training went to 7-on-7. He had a few missed opportunities later in team meetings and allowed for some degrees, even with tight coverage.
– Offensively Darren Waller ran a great out-and-up route in a duel and Carr joined him on a low pass down the sideline. At his next goal, however, Waller dropped a ball that was thrown behind him, but probably would have had to be caught.
– In 7-on-7 exercises, the seemingly first string defense played much better with rookie safety Johnathan Abram drops two possible interceptions. Linebacker Jason Cabinda also had a nice pass split on a pass for Keon Hatcher.
– The backup quarterback contest continues, as Nathan Peterman took over most of the second string rehearsals on Sunday after Mike Glennon made the first jump with the second team on Day 1. Olson suggested they continue to go back and forth throughout the camp.
– Defensive Attitude Ronald Ollie did not train on Sunday after finishing his training on Saturday.  RELATED: Raiders could train in Napa after Vegas moved. After he had caught a slant, Wilson ran into the end zone, looked at those standing at the back line and shouted: "I still have, man!" before the return flight to midfield.
– Renfrow continued to impress in his work against veteran Lamarcus Joyner in the slot. The Clemson product has a knack for openness and seems to build a fast relationship with Carr.
