Diego Simeone has been dealt a blow for decisive matches in La Liga and the Champions League with the loss of the full-back
Juanfran is expected to miss the first leg of Atletico Madrid's Champions League last-16 tie against Bayer Leverkusen due to a hamstring injury, while his availability to face Barcelona is also in doubt.
The right-back underwent an MRI scan which revealed a "grade I-II" strain to the right hamstring, with the minimum expected recovery time reported to be two weeks.
Juanfran sustained the injury during Atletico's 3-2 LaLiga victory over Celta Vigo on Sunday and was forced off at half-time.
