Madrid - Sevilla's injured French striker Kevin Gameiro will miss the visit of English champion Manchester City in a crucial Champions League clash on Tuesday.
Gameiro is Sevilla's top scorer so far this season with seven goals in 14 appearances.
But the diminutive striker suffered a hamstring injury in the Europa League holder's 2-1 defeat at Villarreal on Saturday.
Sevilla remains hopeful he could return to face Real Madrid in Seville next weekend.
"Gameiro suffered a grade one tear in his left hamstring according to tests carried out this morning," Sevilla said on its website Sunday.
"The injury will prevent him playing on Tuesday against Manchester City," the statement confirmed.
