The Soweto giants endured a week-long intensive camp ahead of the new 2018/19 campaign which is scheduled to start next month.
The players trained under the tutelage of Bucs head coach Milutin 'Micho' Sredojevic and his technical team in Nelspruit.
On Saturday, Bucs' new coach goalkeeper coach Andrew Sparkes posted a photo of himself and the team's shot-stoppers.

Reports indicated that unnamed Brazilian players are currently on trial at the Soweto giants emerged.
The trainer has been busy working with Pirates keepers Brilliant Khuzwayo, Siyabonga Mpontshane, Jackson Mabokgwane and Wayne Sandilands.
Goal contacted Pirates' administrative manager Floyd Mbele, who confirmed the presence of the trialists.
"Yes, we do have trialists, who are training with the team," Mbele told Goal.
"But we will soon reveal their identities in a club statement," the Bucs admin boss added.
Bucs are expected to travel back to Johannesburg on Sunday before flying out to Zambia on Monday.
The Zambian leg of the Bucs camp will focus mainly on matches as the team nears the start of the new season.
Sredojevic and his highly-rated assistant Rulani Mokwena are currently dealing with 45 players.
However, as the pre-season progresses, the technical team will reduce the playing complement to a manageable number, before the new campaign starts.
