The Charleston Battery of USL PRO announced the signings Wednesday of midfielders Tony Donatelli and Ryan Richter and defender Cody Ellison.
Donatelli played last season season for the Rochester Rhinos.
He began his professional career with the Vancouver Whitecaps in the USL First Division in 2006, leading them to a championship. After the 2008 season, he was traded to the Montreal Impact and led them to the 2009 USL-1 championship in a victory, ironically, over Vancouver.
Donatelli, who played four seasons at Temple, was signed by Major League Soccer's San Jose Earthquakes in January 2011 but was waived before that season began.
Richter, who attended LaSalle University, was drafted fifth overall in the 2011 MLS Supplemental Draft by the Philadelphia Union but later was loaned to USL PRO's Harrisburg City Islanders.
Ellison played with Battery midfielder Jose Cuevas on the 2011 Fresno Fuego team in the USL Premier Development League.
