Gonzalo Higuain had to be stretchered off despite playing on in Juventus’ draw with Lecce after a nasty blow to the head.
As the Serie A leaders chased a winner at Stadio Comunale Via del Mare, he collided with Brazilian keeper Gabriel.
Pictures show how blood immediately poured out of a cut on Higuain’s forehead as physios attended to him.
A huge bandage was wrapped around the striker’s head before he amazingly played on.
But there will be big questions over why he was allowed to do so after he required a stretcher to leave the pitch at full-time.
Higuain, 31, did not appear to be knocked out by the blow but could have been concussed to some extent.
After the 1-1 draw, it was confirmed he was taken to hospital for checks.
The incident provided Juventus with seven minutes of stoppage time to try and find a winner but left Lecce with just a point.
It was a tale of two penalties with Marco Mancosu levelling up after Paulo Dybala’s spot-kick.
Cristiano Ronald was rested for the game by Maurizio Sarri.
And the Old Lady will lose their lead atop Serie A later on Saturday if Inter Milan claim victory at home to Parma.
