Exeter Chiefs will be sweating over the fitness of international flanker Tom Johnson after he suffered an injury early in their loss to Leinster.
The 30-year-old England back-row forward left the field on a stretcher after just fifteen minutes, with coach Rob Baxter explaining the current situation.
"He's done something to his knee and his ankle," he told BBC Radio Devon.
"Until we get it scanned we're not going to know how serious it is."
Johnson was withdrawn from England's Elite Player Squad on Sunday and replaced by Worcester Warriors youngster Matt Kvesic.
