Juanfran could feature for Atlético Madrid in Thursday's Europa League clash with Sporting CP after recovering from a hamstring injury.
The right-back was hurt in the second leg of his side's last-16 tie against Lokomotiv Moscow on March 15 and was subbed at half-time by coach Diego Simeone.
Juanfran back in training this week after return to fitness
The Spain international has since sat out LaLiga fixtures against Villarreal and Deportivo La Coruña but returned to training with the first-team squad earlier this week.
Atlético confirmed Juanfran will be available for the first leg of the quarter-final tie against the Portuguese club at the Wanda Metropolitano.
The defender's return is timely, with fellow full-back Sime Vrsaljko not included in Simeone's 18-man squad.
