Elzayat of Egypt suffered a blow to his neck during his men's K44 under-61-kilogram semi-final match against Daniil Sidorov of the Russian Paralympic Committee (RPC) at the Makuhari Messe Hall B in Chiba.

The referee was forced to stop the fight, awarding the victory to Elzayat, who left the arena on the a stretcher after Sidorov was disqualified for a high kick.

A dazed Elzayat managed to take to the mat for the final against Brazil’s Nathan Cesar Sodario Torquato only for it to be cut short by the referee due to the Egyptian’s condition.

After being helped off the mat, Elzayat was once again put on a stretcher before leaving the arena.

The 20-year-old attended the victory ceremony to collect his silver medal but confirmed he still needed to go to hospital to receive further treatment.

"I am so happy with this medal," said Elzayat.

"This [his neck and shoulder] is very, very sore."

When asked what happened in the semi-final against Sidorov, Elzayat added: "In the semi-final I was kicked here [his neck].

"I couldn't make the final.

"It was finished [for me]."

"There was a taxi that went to the hospital and brought me here again [for the medal ceremony]. 

"I have to go there [hospital] again."

Sodario Torquato became the first male taekwondo fighter to win Paralympic gold as Mahmut Bozteke of Turkey and Sidorov clinched bronze medals.

"But I feel proud and happy for the result.

"I want to tell all Peruvians."
