Dolphins running back Reggie Bush has played his last game as a member of the Miami franchise, according to the Miami Hearld on Sunday. Bush, who put up career highs in rushing since joining the Dolphins two years ago, will be testing the free agent market according to an unnamed source close to the running back.

Three teams have expressed interest in Bush, contacting the running back once the NFL's three-day negotiating period opened Saturday at midnight. However, the Dolphins haven't shown any interest in retaining him, the source told the newspaper.

Miami is said to have interest in having Lamar Miller and Daniel Thomas at the running back position in 2013.

The 28-year old Bush rushed for 2,072 yards and 12 touchdowns while a part of the Dolphins offense. In 2012, Bush played in every game for the first time since being drafted by New Orleans in 2006. The former college standout fell just shy of his second consecutive 1,000-yard rushing season, finishing with 986.
