He was hit on the final play of the first half and didn't return. He was ruled out in the fourth quarter.
Backup Matt Moore replaced Cutler at quarterback to start the third quarter and finished 17-of-28 for 282 yards and a touchdown.
Cutler got what is -- at least -- his third concussion in the past seven years in Sunday's loss, and now coach Adam Gase has a big question to deal with as the Dolphins prepare to visit the New England Patriots next week.
"I want to get to tomorrow first and see how he's feeling,'' Gase said on whether to move forward with Cutler or Moore.
Cutler had three interceptions against the Bucs in what was his first multi-interception game of the season and worst half of the year.
This is the second time Moore has replaced Cutler this season. Cutler broke multiple ribs earlier this season, causing him to miss one game.
"I was just the same as always: work the offense, communicate, execute, and get in the flow of the game,'' Moore said.
The Dolphins signed Cutler to a one-year, $10 million contract in August to replace former starting quarterback Ryan Tannehill, who suffered a season-ending knee injury.
