Jofra Archer finds himself in the middle of a beamer row after South Africa's Vernon Philander hinted that the England seamer should have been removed from the attack on day two of the Boxing Day Test.
Archer was bowling to nightwatchman Anrich Nortje late on a difficult second day for the tourists in Centurion – they closed 175 behind with six second-innings wickets still to take after being bowled out for 181 – when he sent down successive high full tosses.
Neither delivery was propelled at the breakneck pace Archer is capable of, with both appearing to be botched variations on his slower 'knuckle ball', but Nortje was visibly rattled as he twice collapsed to the turf to avoid being struck.
Philander had earlier bowled outstandingly as he claimed four for 16 and was just as uncompromising as he assessed the drama surrounding his fellow paceman.
"The umpires have to deal with it and make the right call," he said.
"I suppose if you're at square leg and you call 'no-ball' you've got to stand your ground. At no time did they actually cancel it (Reiffel's signal).
"I don't know what happened but there was a little bit of a conversation going on after the game. For me it's plain and simple, we're playing a game and we're setting an example for the rest of the people coming into this game.
"Are we going to tolerate it at another game or are we going to put a stop to it right here?"
Asked if his disciplined performance, which ripped the life out of England's innings, was an example that elaborate but risky variations were not necessary, Philander risked needling Archer by adding: "That's why it's called the purest format: don't try silly things that can cost you not bowling another ball in the innings."
Almost as an aside the 34-year-old confirmed reports he would be joining Somerset as a Kolpak player once he retires from international duty at the end of the series.
"Somerset? Everyone knows it. We're going to go year by year," he said.
England clearly took a different view to Philander about Archer, with Joe Denly seeking to downplay the late tension.
"The first one, fair enough, he didn't quite get it right," offered the batsman.
"He's bowled that a lot for us and it's worked pretty well but I wasn't expecting the second one if I'm totally honest. It just missed the stumps so I thought it was a fair enough delivery.
"I saw (Reiffel) put his arm out and I think he tucked it in again as well. I was talking to Gaffaney and I think he said they withdrew the second one."
