Tour doctor James Robson told the sorry tale about the Irish back row man at his medical briefing after the game.
"Stephen is the leading contender for the most bizarre injury on tour. He injured a muscle in his lower leg as he slipped getting off the team bus," said Robson.
"The good thing is that he is now no longer injured, back in training and available for selection."
Dr Robson knows a thing or two about rugby injuries having been the Lions' team doctor since 1993. He has also worked with the Scottish team since 1991.
So if Ferris' problem was a new one on him, the rest of injury concerns after the game in Phokeng were reasonably routine.
The full Lions injury roll call was as follows:
Mike Blair - rolled left ankle, back in training early part of the week.
Keith Earls - a prop landed on his shoulder, which was very sore after the game. Back in training mid-week.
Stephen Ferris - a mild strain of a lower leg muscle getting off the team bus. Now no longer injured.
Luke Fitzgerald - has a slight chest infection and a mild strain of the knee.
Riki Flutey - strained his right knee slightly in his 14 minutes on the field as a replacement on Saturday. Had treatement after the game.
Paul O'Connell - had antiseptic drops put in his eye and had to wear a patch after receiving a corneal scratch during the game. Also had some fluid drained off one of his ears.
Mike Phillips - suffered a slight dead leg which was iced overnight.
Andy Powell - now back in training after taking a heavy knock on his right hand, probably after hitting someone's head.
Leigh Halfpenny - now fully fit having rejoined the Lions in South Africa.
In addition to this list, 20 players have been bitten by insects.
"I'm very happy with the injury list at present. In 1987 we had 18 players injured half way through the tour," recalled Robson.
"The current crop all fall into the category of bumps and bruises."
