Colchoneros seem to be in the soup as for line-up to align in next challenges on European scale. Atletico play Livepool at the Wanda Metropolitano on February 18 and will be desperate to have Morata fit, given their lack of options up front. Diego Costa and Joao Felix are both currently out injured.
"Alvaro Morata has suffered a muscular injury in his right leg," a club statement read. "His return will depend on his recovery."
Morata had to come off in the second half of Atletico's 1-0 defeat by Real Madrid in the city derby in La Liga on Saturday.
