Mohomi trained with Gallants last season but failed to secure a contract with the Limpopo-based side. The former Brazilians midfielder later resurfaced at Baroka FC for assessment but was still not lucky enough to sign at the club.
The 31-year-old has since joined Gallants for their pre-season training and was featured during a friendly match against Kaizer Chiefs played in Polokwane over the past weekend.
"Mohomi is training with us. He has been given a chance like everyone who is here to impress the coach," said an official at Gallants.
"We have a few other trialists here. It's still early to decide whom to sign. The coach will continue to assess Mohomi with the other players during the pre-season training," he added.
Gallants are to be led by Romain Folz this coming season.
