Injured Jones could miss Scarlets’ Cup clash against Munster
Jones aggravated the injury in training and will be out of action for around three weeks, which leaves him a major doubt for the Llanelli Scarlets’ Heineken Cup quarter-final against Munster on March 30.
Wales head coach Gareth Jenkins reacted to the unexpected news by promoting Thomas from the bench to lead the team from inside centre with James Hook shifting to fly-half.
