England coach Eddie Jones will be hoping that the stomach muscle injury Danny Care sustained in Premiership action is not too serious.
Care is an important cog in Jones' side having been named as vice-captain and selected as only one of two scrumhalves for the upcoming tour of Argentina.
However, the Harlequins scrum-half hobbled off after just 26 minutes of his side's 32-12 victory over Wasps on Friday.
Harlequins director of rugby John Kingston was unaware as to the extent of the injury when he told Club Call: "Danny has an oblique injury and struggled to run it off. He's probably stretched it and may have pulled it.
"There are eight days until the next game so we'll have to see how he scrubs up, but we don't know at this stage."
Jones was in the stands watching the Premiership clash and will be sweating over the fitness of Care as the England players will gather in London at the end of this month to begin preparations for the first Test against the Pumas taking place on June 10.
