England head coach Stuart Lancaster will be sweating on the fitness of flank Tom Wood and lock Geoff Parling after the pair limped off on Saturday.
The Northampton and Leicester players were forced to leave the field in their respective Champions Cup games against Racing and Ulster.
And with England’s opening Six Nations clash against Wales less than two weeks away, it appears it will be a race against time for the pair.
Parling though is unlikely to be fit for the Millennium Stadium fixture, with Tigers boss Richard Cockerill giving an update.on his second-row.
“It is a bit soon to say, he has hurt his MCL [medial cruciate ligament] on the inside of his knee and we will see how bad that is but it will be a few weeks I would imagine,” he told The Telegraph.
“It is nothing too drastic but it will be three to four weeks probably.
“He will come back with us tonight and be assessed by our medical people and he will obviously go to England and report there and have the assessment.”
Wood’s return date meanwhile could be sooner as he awaits further news on his ankle problem, with boss Jim Mallinder more positive on his player’s fate.
