The defender will definitely be out of the Flames crucial 2013 Africa Cup of Nations qualifier against Chad at the end of this month.
Nyirenda, who scored in FlamesÃ¢â‚¬â„¢ last Afcon qualifier in October in Chad, said he got injured in a friendly encounter for his South African Premier Soccer League side Black Leopards.
“Just coming from an X-ray and going for a PoP (Plaster of Paris). I will be out for six weeks. Please, pray for me to get well soon,” he posted on his Facebook wall.
In an interview with Nation on Sunday, Nyirenda said he is sad with injury as he is set to mix his clubÃ¢â‚¬â„¢s seven league games.
“It is a blow to me personally as my career will be derailed but also to Leopards as we are fighting relegation. It is my hope that I get back in action before the said time,” he said.
The former Wanderers defender established himself as a Flames regular after playing four consecutive games last year in the absence of then injured captain Peter Mponda.
Flames coach Kinnah Phiri described NyirendaÃ¢â‚¬â„¢s injury as a blow, although he said he is yet to get official communication on the matter.
“Harry [Nyirenda] is a key player of the team at the moment. It is a blow to our preparations, but I will say more when I get an official communication from his club,” said Kinnah.
Meanwhile, defender Elvis Kafoteka, who is trying his luck in Asia has also ruled himself out of the Chad game, saying it would be difficult to come as he may struggle to go back due to visa complications.
