Ben Spies has withdrawn from the remainder of this weekend's Italian MotoGP.
After missing the past two rounds to undergo further rehabilitation on his healing shoulder, the Texan returned to action on Friday at Mugello, when he was 16th fastest.
The following statement was then released by the Pramac Ducati team on Saturday morning:
“Unfortunately yesterday's free practice sessions highlighted the muscular problems still afflicting Ben Spies.
“The intense rehabilitation activities which the Texan has undergone in the last 4 weeks have brought about a clear improvement but it still not sufficient for Spies to demonstrate his true potential on the track.
“After an analysis of the situation, the Pramac Racing Team, Ducati Corse and the rider have taken the mutual decision to continue rehabilitation and physiotherapy and to interrupt all track activities to allow Ben to complete his total physical recovery.
“In the next few days Ben Spies will undergo further medical checks in order to have a clearer appraisal of the situation and evaluate the treatment to be followed for full recovery.”
