Tua Tagovailoa, the Miami Dolphins quarterback, is listed as questionable for the upcoming game against the Cardinals but is on track to play after fully practicing on Thursday and Friday. He has cleared the NFL's concussion protocol and is expected to provide a significant boost to the Dolphins' offense, which has struggled in his absence. The team has averaged just 10 points per game over the last four contests without him.

• Tua Tagovailoa is likely to return to action this weekend against the Cardinals.
• The Dolphins' offense has struggled significantly without him, averaging just 10 points per game.
• Uncertainty remains regarding who will back him up if he doesn't play, as other QBs on the roster are dealing with injuries.
