An injury to Harlequins tighthead Kyle Sinckler marred a tense affair with Leicester Tigers at Big Game 12 at Twickenham.
The game saw Premiership strugglers Leicester Tigers battled back to draw 30-30 with Harlequins in front of 75,000 supporters.
Sinckler – clearly in some discomfort – had to be helped from the field in the 65th minute after being involved in a heavy collision in Tigers’ twenty-two.
On Sinckler's injury ahead of the Six Nations, Harlequins head of rugby Paul Gustard said: "It's too early to tell to be honest.
"I don't think he's even been assessed yet, so I can't even tell you which part of the body hurts him."
