FORMER Lancashire chairman Jack Simmons is pioneering the introduction of yellow cards into county cricket.

Players could be sent from the field for a set number of overs for abusing umpires or excessive sledging if trials at minor county level prove a success.

"Jack Simmons (pictured) and Mike Griffith, the chairmen of the ECB and MCC cricket committees, are very concerned and, if the trials work, would want this as part of the first-class game, although much cricket at that level is self-policed," said ECB chairman Giles Clarke.
