RIO DE JANEIRO - Dual World Cup winner Ronaldo has missed a celebration marking the 101st anniversary of Cruzeiro, the Brazilian club in which he acquired a controlling stake last month, after being diagnosed with COVID-19.

The 45-year-old has only mild symptoms but will rest and isolate in line with health protocols, Cruzeiro said on Sunday.

"Cruzeiro announces that this Sunday morning Ronaldo Nazario tested positive for COVID-19," read a club statement. "This makes it impossible for him to go to Belo Horizonte for the commemorative festivities."

The event had been earmarked as Ronaldo's first public appearance since he completed the purchase of a majority stake in Cruzeiro for 400 million reais (around 70 million US dollars) last month.

"Ronaldo is sorry for not being able to participate in the activities planned for the next few days, but soon we will announce a new schedule for his arrival in Belo Horizonte," the statement added.
