Wallace cleared concussion protocols Friday and will play Sunday versus the Dolphins, Adam Schefter of ESPN reports.
Wallace will return to the field in Week 7 after missing the Steelers' Week 6 win over the Buccaneers while dealing with a concussion. The cornerback will step back into his prominent role in Pittsburgh's secondary. On the year, Wallace has produced 13 tackles while deflecting four passes and intercepting another over five contests.
