Andy Farrell leaves the pitch at Vicarage Road after being injured

Saracens and England centre Andy Farrell will miss the rest of the season after picking up an injury in the Heineken Cup win over Ospreys.

The 32-year-old former rugby league international suffered a shoulder injury and is certain to miss Saracens' first Heineken Cup semi-final.

"He has a total rupture of his AC joint so he will be gone for about three months," said coach Alan Gaffney.

The injury also rules Farrell out of England's summer tour to New Zealand.
