Three days into training camp, the Bucs made two roster moves, signing former Titans safety Marqueston Huff and former Oklahoma State receiver Jhajuan Seales.
To make room for the moves, the Bucs waived a pair of undrafted rookies in safety Alex Gray and receiver Thomas Sperbeck. Sperbeck had been held out of Sunday's practice with an unspecified injury.
Huff, 25, played two full season with the Titans in 2014-15, totaling 36 tackles and returning an Eli Manning pass 23 yards for a touchdown in 2014. He tied for the Titans' team lead in 2015 with seven special-teams tackles.
