MEXICO CITY, July 15 (Xinhua) -- Guadalajara manager Luis Fernando Tena has tested positive for COVID-19, the Liga MX club said on Wednesday.
The 62-year-old is asymptomatic but will be placed under medical supervision during a mandatory isolation period, according to a club statement.
"We received the results of 52 tests this morning, among which the one from our head coach Luis Fernando Tena was positive," it read.
The announcement came eight days before the scheduled start of the Liga MX Apertura tournament. The Liga MX called off its Clausura league season in May, having suspended the competition on March 15 because of the pandemic.
Tena thanked fans for their support and goodwill in a message posted by Guadalajara on social media.
"In general, I am well and feeling strong to fight this virus," he said. "I don't think I'll be ready for the first match of the season but I have full confidence in [assistants] Chava Reyes and Alberto Coyote."
Guadalajara, who are also known as Chivas, will begin their Apertura campaign with a home match against Leon on July 25.
Mexico has over 317,000 confirmed COVID-19 cases, of which more than 36,000 have been fatal.
