Playing for Bridgend against the All Blacks in 1978, Williams was caught at the bottom of a ruck, where he was stamped on by the opposing prop John Ashworth and had a hole torn in his cheek.
Unfazed, Williams, a trained surgeon, retired from the pitch, stitched up his own injuries, and returned to the field. What a legend.
Adi Jacobs of the Sharks suffered a similar fate against the Blues, but it was purely accidental as Doug Howlett’s foot came down on his face after a tackle. You can view the video of it here.
