England scrumhalf Dan Robson 'devastated' after suffering 'blood clots'

England’s replacement scrum-half Dan Robson has suffered blood clotting which could end his season.

Earlier in the week Robson underwent medical checks after being ruled out of today's Guinness Six Nations clash with Scotland through illness.

Wasps and England Rugby both confirmed that Robson suffered "blood clots which arose spontaneously earlier this week and is being evaluated and treated by specialists at the moment.

"At this stage it is too early to give a return-to-play date."

The devastated Robson tweeted the following picture message.

'Obviously pretty devastated by my recent news but I know I am in the best hands to get back to full health and back on the pitch as soon as I can.

"Appreciate all the support from everyone and a special out to the medical staff that have aided me especially in locating the issue and acting so promptly."

Robson was poised to win his third cap as Ben Youngs’ understudy for the climax to the tournament at Twickenham but will now be replaced on the bench by Saracens’ Ben Spencer.

“Dan is not available and has left camp. He’s got some investigations and consultations going on. We’re trying to investigate exactly what’s wrong,” forwards coach Steve Borthwick said during the week.

Spencer won both of his caps as a replacement on last year’s tour to South Africa and Borthwick views his former Saracens team-mate as a ready-made replacement for Robson.

“I was fortunate enough to play with Ben. He’s a good player. He’s fast, fit and has real good fundamentals of the game. He can pass well and kicks well,” Borthwick added.

“He’s had time with us last year and knows our principles of play. He’s played with and against a lot of the players here, so knows them well.”
