Earlier this week, reports from Brazil stated Telles had tested positive and would therefore miss his country's important World Cup qualifying match in Montevideo.
Medical staff at the Aon Training Complex were monitoring the situation and our update on Monday confirmed the club would make an assessment when Telles returns to England later this week.
However, since then, the Brazil Football Confederation has published a positive update on Telles and his availability with a statement via their official website.
“The defender already had the disease, was asymptomatic and with a non-transmissible condition of the virus, but he could not travel to Uruguay,” the update reads.
