Antonio Brown marked the beginning of his Raiders tenure with an over-the-top arrival.

Brown, who was traded from Pittsburgh to Oakland during the offseason, flew in a hot air balloon over Napa Valley to get to his first training camp with his new team.

“Is he OK? That’s all I want to know,” Raiders coach Jon Gruden joked to reporters. “I expect a lot more drama from No. 84. I really do.

“I told Antonio, ‘Try not to yell at Derek [Carr] — yell at me when you have a problem.’ Then he started yelling at me. I said, ‘Don’t yell at me — yell at [Greg] Olson. He’s the offensive coordinator.’ [Brown] is a fun guy to be around, man. I expected a little bit more than a hot air balloon; I thought he might jump out of an airplane and parachute here himself, but he’s going to add a lot of life to this organization at a position where, obviously, we need some explosive plays.”

Video of Brown in the balloon was published on the Raiders’ Twitter account.

“I thought it’d be exciting to switch it up,” Brown says in the video. “Napa Valley obviously is known for the hot air balloons. This camp is so important for this team because there’s a lot at stake. We’ve kind of got to develop our identity.”

Brown won’t actually be starting camp on the field as he was placed on the non-football injury list. ESPN reports the undisclosed injury isn’t considered serious.

It should all make for an interesting start to “Hard Knocks” this summer as the Raiders will be under the HBO microscope.
