Not good.

Munster look set to be without centre Chris Farrell for their crucial Champions Cup quarter final clash with Toulon at Thomond Park.

The Ireland centre injured his knee at training yesterday, and has been ruled out of the rest of the Six Nations championship. Farrell was named man of the match in a superb performance against Wales on Saturday.

The42 are reporting that Farrell picked up an an ACL injury and may be severe enough that he will miss the rest of this season. The report also says that Farrell will undergo surgery on his knee in the next week.

Jaco Taute is also still out injured for Munster, also with a sever knee injury, meaning Sammy Arnold is in line to fill it at outside centre for the clash against the French giants and beyond.

21-year-old Arnold has once again been training with the Ireland squad this week.
