Gamildien was handed a two-match suspension by the club after he was found guilty of misconduct during the league match against Chippa United a few weeks ago.
The former Bloemfontein Celtic forward was given a red card for descent during the game against United and the Dube Birds hailed him before the club's DC for misconduct.
Swallows boss David Mogashoa has confirmed that Gamaldien has completed his suspension and is ready to play again.
"It's related to the incident that happened during the league match against Chippa United. The club condemns misconduct in the strongest terms," Mogashoa tells snl24.com/kickoff.
"He has completed his suspension. Everything is okay and he should be ready to play in the next match against Stellenbosch."
