Gibson injured his knee when he landed awkwardly in the first half of a 27-17 loss to the New England Patriots on Sunday.
Gibson was a dependable receiver who had 30 receptions for 326 yards and three touchdowns. He caught all three touchdowns in Miami's last two games.
The Dolphins are thin at receiver and will most likely add another player at that position soon. Miami currently has Mike Wallace, Brian Hartline and second-year receiver Rishard Matthews on the 53-man roster. Ryan Spadola and Nathan Palmer also are on the practice squad.
Miami (3-4) will play the Cincinnati Bengals (6-2) on Thursday night.
