Cardinals rookie cornerback Patrick Peterson says he and his classmates are being kept in the dark on the NFL labor front. "I haven't heard any news about what you just discussed," Peterson said, referring to the recent ruling from the 8th Circuit that affected rookies and free agents. "It's confidential -- those guys aren't telling us anything. The only guy in the rookie class is Von Miller, and I know him personally, and he's not saying anything as well. "So those guys have to stay true to what's going on in court."
