Manchester United winger Facundo Pellistri has suffered an injury setback with loan club Alaves.
Pellistri was substituted in the game with Celta Vigo at the weekend, and Alaves have now reported back on the result of tests on his injury.
They said: "Facundo Pellistri left last Sunday the match against RC Celta de Vigo with some muscular discomfort and yesterday Tuesday he underwent tests to determine the exact extent of the same.
"The medical report of IMQ reveals that the Uruguayan player suffers a fibrillar tear in the short portion of the left femoral biceps that has prevented him from exercising with his teammates.
"Pellistri will follow a conservative treatment and his evolution on a day-to-day basis will mark his availability to join the group."
