Pittsburgh Steelers cornerback Joey Porter Jr. is unlikely to play in Sunday's season opener against the Atlanta Falcons due to a back injury, per ESPN and NFL Network reporting. Porter is listed as questionable for the game.

The 24-year-old has been at the center of a contract dispute throughout the offseason and did not participate in training camp. Head coach Mike Tomlin said Porter is still being "ramped up," according to one report. A trade remains a possibility for the former second-round pick, per Schefter and Rapoport.

The exact timeline for Porter's return and the likelihood of a trade were not detailed in the available reporting.
