MIAMI (AP) - Receiver Brandon Gibson has signed with the Miami Dolphins, giving young quarterback Ryan Tannehill a third new target through free agency.

The Dolphins also added receiver Mike Wallace and tight end Dustin Keller this week. Last week they re-signed receiver Brian Hartline.

Gibson, who signed Friday, spent the past four seasons with the St. Louis Rams, where he made 38 starts. Last year he had 51 receptions for a career-high 691 yards and five touchdowns while starting 13 games.
