Moore originally signed with Miami in 2010 as an undrafted free agent. He played in 35 games over three seasons with the Dolphins, including two starts, and recorded 12 receptions for yards and two touchdowns. After spending the first eight weeks of the 2013 season with the San Francisco 49ers, including six games played with one reception for six yards, he was released last week.
Spadola, meanwhile, was promoted from the Dolphins' practice squad this past weekend, and appeared in seven special teams plays. He joined Miami at the beginning of October after being waived by the New York Jets. He was expected to re-sign with New York, joining their practice squad, but instead he chose to head south to Miami.
The Dolphins lost receiver Brandon Gibson to a season ending knee injury during their Week 8 loss to the New England Patriots. Moore will likely fill in as the fourth wide receiver on the active roster, with Rishard Matthews taking Gibson's slot position.
