The next driver to act as a F1 steward in 2010 will be Alex Wurz.
Wurz to be Chinese GP steward
FIA president Jean Todt's new scheme, where an experienced former driver sits alongside the three other stewards at Grands Prix, is designed to add credibility to their decisions.
Alain Prost fulfilled the role in Bahrain, followed by eight time Le Mans winner Tom Kristensen in Australia and then Johnny Herbert at last weekend's Malaysian Grand Prix.
Austrian Wurz, 36, will be the fourth steward at the Chinese Grand Prix in Shanghai next weekend, according to Germany's Passauer Neue Presse.
He last raced in F1 with Williams in 2007.
