The Cowboys officially waived safety Ahmad Dixon Monday morning.
Dixon made headlines from the time Dallas selected the controversial defensive back out of Baylor in the seventh round, all the way up until his release from the roster Monday.
The hard-hitting safety led the Cowboys in tackles in the preseason opener against San Diego despite leaving that game with concussion symptoms. He showed up late to the final walk-through of training camp and sat out the second preseason game, before being fined for an illegal hit in the third game against Miami.
Dixon missed much of May's rookie minicamp early in the summer with a groin injury.
He joins CB Terrance Mitchell and LB Will Smith as the three seventh-rounders to be released by the Cowboys during roster cuts.
The Cowboys also signed safety C.J. Spillman, who was cut by the 49ers Saturday, to the 53-man roster and fullback Nikita Whitlock to the practice squad on Monday.
If Dixon clears waivers, the Cowboys could sign him to their practice squad.
