England and Wasps scrum-half Dan Robson faces an indeterminate spell on the sidelines after developing blood clots – potentially jeopardising his World Cup hopes.
Robson earned his second England cap last weekend, when he came off the bench to score his first international try in the 57-14 thrashing of Italy in the Guinness Six Nations.
The 27-year-old would have been expected to retain his place among the substitutes for Saturday’s closing Six Nations match against Scotland at Twickenham but was ruled out in midweek through illness.
Wasps have now confirmed why Robson’s Championship is over as they said in a brief statement: “Dan Robson suffered blood clots which arose spontaneously earlier this week and (he) is being evaluated and treated by specialists at the moment.
“At this stage it is too early to give a return-to-play date.”
Robson was replaced in England’s squad by Saracens number nine Ben Spencer, who will provide half-back cover for Ben Youngs.
