Knee injury puts Dan Biggar doubtful for England's Six Nations clash

Wales international Dan Biggar is a doubtful starter for the upcoming Six Nations clash against England following a knee injury.

The 30-year-old sustained the injury while playing for his club Northampton Saints in the recently concluded Gallagher Premiership game against Saracens at Franklin's Gardens where he limped off the field in the 20th minute.

Northampton Saints director of rugby Chris Boyd said a call on Biggar's fitness level will be taken only after further assessment.

"I don't think it is [a bad injury]. He's hyper-extended his leg in a collision and he seems to be moving relatively OK.

"I don't think he's got any major structural damage from what I'm led to believe, so it's one of those ones where we'll wait and see."

Biggar has played 82 Tests for Wales since his debut in 2008 and has gone on to amass over 400 points.

Wales are already without Josh Adams, who was sidelined with an ankle injury while George North will undergo return to play protocols after sustaining a head injury during the match against France.

Wales are positioned fourth in the Six Nations table with a solitary win from three games and will face England and Scotland in the final two rounds.
