Demps made his NFL debut last year, appearing in two games after joining the Bucs following the close of his track and field season. He was a member of the 2012 U.S. Olympic 4x100 relay team that won a silver medal at London, and initially entered the NFL as an undrafted free agent with New England.
Unable to obtain a full-time commitment from Demps, the Patriots traded him to Tampa Bay in exchange for LeGarrette Blount in April 2013.
Tight end Cameron Brate, linebacker Brandon Magee, defensive tackle Matthew Masifilo and receiver Solomon Patton also were waived.
