AC Milan midfielder Kevin Prince Boateng paid a jersey tribute to his team-mate Antonio Cassano who has suffered a strange illness in Italy.
The Ghana international made the gesture during a 1-1 draw with BATE Borisov in the Champions League on Tuesday.
Cassano suffered sudden and alarming loss of physical control while with Milan teammates flying back from the victory at Roma on Saturday night.
Boateng removed his shirt to show a "Cassano 99" Milan short underneath, in solidarity with his teammate who is rumoured to have suffered a stroke.
"I hope that Antonio will be back soon to play and all my prayers are with him," the Ghana international said.
It was confirmed Cassano has suffered a cerebral problem related to an ischaemic stroke.
He is due to undergo an operation to close a small hole in his heart.
While the condition is not a particularly rare one and usually caused little to no affects in the sufferer, he is expected to be out for several months.
