Cardiff Blues centre Jamie Roberts could be a doubt for Wales's Six Nations campaign due to a knee injury.

The 25-year-old sustained the problem as the Blues defeated Newport 28-9 yesterday evening.

Roberts had only been on the pitch since the break but required treatment on the complaint on two separate occasions.

It was then decided that he was unable to continue and he was replaced after 68 minutes.

Wales begin their Six Nations campaign against Ireland on Sunday, February 5.
