Sussex Sharks fast bowler Tymal Mills has suffered an injury setback.

The left-armer is likely to miss the rest of the Vitality Blast campaign with a lumbar spinal injury which he has been told to rest.

This injury is separate to the thoracic spine condition which led to Mills becoming a T20 specialist and dropping out of longer formats.

The news is a big setback for Sussex with Mills in impressive form this season.

He has reported discomfort while playing in the tournament and has been told he requires “an extended period of rest”.
