"He's in a bit of discomfort but there’s nothing untoward and he should be fine for Friday," said Moosajee.
A ball from Wayne Parnell lifted at him and after having his fingers strapped, Boucher was back in the nets.
"We're managing the injury with ice and compression but, if we need to do any further investigations, it will probably be post Friday's game," Moosajee said.
In his medical capacity, Moosajee said he did not foresee any problems but there was always a plan B if necessary.
"There are always contingency plans in place and it would be up to the selectors to decide who to fly out but, for now, we don't even have any concerns."
Ray Jennings had been present at the team's training sessions and was seen working intensively with Boucher on Thursday.
Proteas' captain Hashim Amla said he was impressed with Boucher's decision to seek assistance from someone of such experience.
"Every player has a mentor and Ray was obviously a star wicketkeeper while Bouch was growing up," said Amla.
"I can only see benefit in him seeking assistance from such an experienced player.
"Boucher is a world record holder himself, so to get advice from somebody who played before him - it shows a lot of humility and all credit to him."
