That didn’t take long. Derek Carr and Antonio Brown are already working out together — doing what Brown complained Ben Roethlisberger wouldn’t do.

The new Raiders teammates were spotted by TMZ Sports at a park close to the team’s practice facility getting used to each other. On Saturday night, Oakland landed the previously disgruntled seven-time Pro Bowler from the Steelers for a third-round pick and a fifth-round selection.

Brown and Roethlisberger had a falling-out, which was part of the reason the receiver forced a trade. Brown said they never worked out together in the offseason and only visited each other’s homes once.

“Sometimes things are bigger than just my issues, you know?” Brown recently said on LeBron James’ HBO show, “The Shop.” “If you work for me for nine years, wouldn’t you expect you to know my girlfriend’s name or my dad’s name or my kid or, you know, would you expect me to meet your kid or at least know you on the level of some sort of integrity to know, like, ‘Hey, man, I appreciate what you do.’ ”

It appears the Raiders and Carr are trying to appreciate Brown.
