Jonny Wilkinson has been hit by another injury setback and he will miss Newcastle’s league clash with Gloucester on Sunday.
Wilkinson was forced out of training on Tuesday and medical examinations found he was suffering "an acute injury to his right adductor".
Wilkinson tore his adductor muscle in January, but had returned to full training and was considered fit enough to be named on the bench for Newcastle last weekend, though he did not feature in the 9-6 win over London Irish.
The latest injury is unrelated to the operation Wilkinson had on a hernia last November.
