Source: Tyreek Hill of the Miami Dolphins is expected to play on Sunday

Miami Dolphins wide receiver Tyreek Hill, who was listed as questionable for Sunday's game with a foot injury, is expected to play against the Arizona Cardinals, a source told ESPN's Adam Schefter on Saturday evening.

Earlier in the day, Dolphins quarterback Tua Tagovailoa, who had been in the concussion protocol since Sept. 12 after suffering the third concussion of his career in a loss to the Buffalo Bills, was activated, potentially reuniting Miami's dangerous pass-catch combination .

Tagovailoa, who was placed on injured reserve five days after the injury and missed the team's next four games, returned to practice Wednesday in Miami Gardens and Hill was emotional when he saw him take the field.

“He looked great. It felt like old times,” Hill said Wednesday. “Me and him hit some deep throws today and that made me feel good today. I missed this and I missed him. I told him that I had to invite him and his wife to dinner because I missed him so much.” S— was so beautiful that I almost cried today, as if I had him alone in the lineup he dictated the plays as if he was running the offense, as if I had simply heard his voice.

“I know it sounds crazy, but he’s a big part of this team.”

Miami is 1-3 in the four games Tagovailoa has missed. During that time, the Dolphins' offense ranked last in scoring, 31st in expected offensive points and 29th in yards per game.

Hill's production has declined without Tagovailoa. He is on pace for 833 receiving yards, which would be his lowest total since his rookie season.
