2004
Despite making the Chargers' roster out of training camp, Welker was cut after the first week of the 2004 season and signed with the Miami Dolphins, where he was mostly used on special teams. Playing against the New England Patriots on October 10, Welker became the second player in NFL history to return a kickoff and a punt, kick an extra point and a field goal, and make a tackle in a single game. Then, on December 20, in a Monday Night Football game against the New England Patriots, Welker returned a punt 71 yards to set up a touchdown.
