Avila, 26, had been in fine form for promoted Osasuna – whom he joined in July – before he ruptured his anterior cruciate ligament in January during a 2-0 win over Levante.
At the time he was being strongly linked with a move to Barcelona as injury cover for Luis Suarez, and recent quotes attributed to Avila suggested a move to Camp Nou was close.
Barca ultimately went for Martin Braithwaite from Leganes, with Avila consigned to a lengthy bout of rehabilitation.
But with the coronavirus pandemic causing the season’s suspension in March, the former Huesca attacker could yet take part in 2019-20 once again.
With Osasuna confirming on Tuesday their first-team squad is to resume individual training later this week, they also showed footage of Avila in action at club’s facilities the same day.
A day prior, LaLiga confirmed plans for a staggered return to group training for clubs, with the target being to resume matches in June.
Spain has confirmed over 250,000 cases of COVID-19, more than any other country except the United States.
