'Shabba' opened the scoring 14 minutes in with a chip from 20 yards over backtracking goalkeeper Reyaad Pieterse at Mbombela Stadium on Saturday.
The 32-year-old then netted his 53rd career goal for Chiefs with a drilled finish in the box 20 minutes later following a marauding run down the right flank by man of the match Ramahlwe Mphahlele.
Tshabalala, who also scored with a sublime lob in the recent 3-2 loss to Cape Town City, was forced off the park with a thigh strain just before the hour-mark, but did plenty to win the praise of Komphela.
"Unbelievable," said Komphela when asked about Tshabalala, who is Amakhosi's top scorer this season with eight goals in all competitions.
"Unbelievable and he's still going on and we wish him well. Great servant of the game, a great servant of us, and a great role model.
"We hope he'll get another 300 matches under his belt and he scored unbelievable goals. The goal he scored in Cape Town, that one goes to the archives. One he scored on Saturday a replica, some are amazing. You can only wish him well.
"Let's just pray that he stays healthy, he stays fit. On Saturday you could see we brought him off early because the legs are starting to give. 'Tight' [Joseph Molangoane] as well.
"Tight has been playing 120 minutes and you go back to Acornbush United [in the Nedbank Cup round of 16], playing 90 minutes and 120 against SuperSport [in the Nedbank Cup quarter-finals] and 90 again - it's too much. So we need to find way to at least rest them.
"Shabba came out because he could feel the thigh was starting to give."
