"I basically just want to pick up where I left off," Rainey said. "Offensively, I think I'm good. To get on offense, I have to do more on special teams."
Rainey acknowledged that he was initially upset and confused when he learned prior to the Bengals game that he was being cut.
"It was a surprise to me, it caught me off-guard," Rainey said. "That's the way this business works. I knew that coming into the NFL, but for it to be that sudden, it was crazy to me. I understand what happened."
