Captain’s armband Cristiano Ronaldo angrily threw to floor while playing for Portugal is put up for auction to help pay for baby’s spinal surgery.

The captain’s armband which Cristiano Ronaldo threw to the ground in anger after Portugal’s World Cup qualifier against Serbia has now been put up for auction to help pay for a baby’s medical treatment.

Ronaldo ripped off the armband and slammed it on the stadium after seeing his last-minute goal ruled out in Portugal’s 2-2 draw in Belgrade last week.

Ronaldo was furious after what looked like a legitimate goal, which would have won the game for Portugal, was not given by the referee or his assistants.

Ronaldo’s shot appeared to have crossed the line before being cleared away by Aleksandar Mitrovic’s sliding clearance, but it was not awarded.

After vehemently protesting with the officials – and being booked for dissent, Ronaldo stormed off the field, throwing down the armband in disgust.

Now a charity organization, which is raising money for a six-month-old boy from Serbia with spinal muscular atrophy to undergo surgery, has managed to obtain the armband.

According to the Associated Press, the charity got the armband from a stadium worker who picked it up after Ronaldo threw it away and stormed off before the final whistle.

The group said the armband, which is blue with the capital letter C in white, will be put on an online auction for three days.

And any money received will be used in funding the boy’s treatment.
