The influential openside, who is one of the favourites to skipper the Lions next summer, was taken to hospital to have his finger put back in place and to undergo x-rays to assess the damage.
But rather than complain about his pain or misfortune, Warburton tweeted two pics of his injury - both of which were unsuitable for the squeamish!
The images showed the 24-year-old's misshapen finger before and during the x-ray, with Warburton tweeting, "Finger is finally sorted, won't be signing autographs for a while!" as he left hospital.
"Suddenly dawned on me I may have fingers like Martyn Williams by the time I finish playing!"
And while the injury looks particularly uncomfortable, both Warburton and his club coach Phil Davies are confident will be back in action in a hurry.
"Hopefully he will be back available for next weekend's game against Toulon," added Davies.
