Robert Croft will join the England coaching team for a brief spell ahead of the one-day international series in South Africa.
The Glamorgan coach played 50 ODIs during a five-year international career and was a key performer during the county's limited overs success.
Croft, who was awarded an MBE in the 2013 New Year Honours List for services to cricket, will join the England coaching squad for a 12-day period in the run-up to the five-match ODI series, which begins in Bloemfontein on February 3.
"This is a great opportunity and something I'm looking forward to," Croft told Glamorgan's official website.
"It's extra experience for me and if the opportunity presents itself to help the lads I will. I'm there to observe and primarily be a sounding board for the spin bowlers, but will give any additional help as required.
"It is another opportunity to increase my coaching experience. The November before last I was invited out to work with Andy Flower with the development squad in Sri Lanka and this time it's the full squad in South Africa.
"I'm looking forward to meeting up with two excellent coaches with different styles in Trevor Bayliss and Paul Farbrace and to absorbing their ideas.
"It is always good to have an open mind in the profession you are involved with, you can learn every day, so I hope to pick up things that will help me be a better coach."
England go into the third Test with the Proteas in Johannesburg leading the four match series 1-0 and Croft has also been impressed with how they have performed in limited-overs cricket.
"Looking from afar, this England team seems to have a no-fear attitude at the moment," added Croft.
"There's a confidence about these England players and the side is well balanced in terms of age and experience."
