Allan Donald came under renewed fire on Tuesday when former South Africa allrounder Adrian Kuiper criticised his bowling at the World Cup and suggested he should not be selected again.
Kuiper, one of the veteran fast bowler's former team mates, said: "The bowling attack hasn't gelled and Allan Donald hasn't been a real threat, has he? I think it could be the end of the road for Donald," he told The Citizen newspaper.
"There comes a time in everyone's career. He isn't bowling with confidence and is only at half pace."
Donald, due to retire after the tournament, has taken one wicket for 106 runs in two Group B matches. South Africa already need other results to go their way if they are to reach the second round.
Donald played in the defeats by West Indies and New Zealand but was not selected for the easy victory over Kenya.
"Why didn't we play Allan against Kenya? If he was lacking form he should have played," Kuiper added.
Donald had been heavily criticised in the media and by his own supporters during the tournament.
The 36-year-old was nicknamed 'White Lightning' in his pomp. He is the only South African to take 300 test wickets, and has 272 one-day victims.
Cricket bible Wisden named Donald as their second-best one-day bowler of all time behind Pakistan's Wasim Akram.
Kuiper played one Test and 25 one-dayers, the last in January 1996.
