GLOUCESTER Rugby will continue to investigate and monitor the fitness of England prop Phil Vickery, who has suffered a recurrence of a long-standing back injury.
The Kingsholm tighthead prop, who has been ruled out of England's squad for their opening RBS Six Nations meeting with Wales next month, has sustained a recurrence of previous back trouble due to a recurrent disc protrusion which is undergoing treatment at the moment.
Vickery suffered the set-back following Gloucester's 19-9 Guinness Premiership victory over Saracens and at present, the seriousness of the injury is not known.
Gloucester's head coach Dean Ryan said: "Phil has been exceptionally unlucky with injuries in the past but our medical team is in control of the situation and they will continue to investigate and treat the problem.
"The injury is being controlled by the right people but as yet there is no definite indication of how long he will be unavailable.
"Phil has suffered previous back trouble in the past and for that reason we need to ensure we follow the right procedures."
England head coach Andy Robinson added: "Phil Vickery was not considered for the game against Wales because of a back injury and in conjunction with his club Gloucester, we will monitor his progress in the coming weeks."

Gloucester's much changed side had to overcome conceding an early try on Thursday evening, but responded in style to down Stade Rochelais by 35 points to 14 in the European Rugby Challenge Cup and set up a mouthwatering return fixture next weekend.
After taking 11 points from their last three games in the Aviva Premiership, including bonus point wins against Wasps and Bristol, Gloucester will be looking to continue their good form when they welcome La Rochelle to Kingsholm.
