Man Utd's Casemiro to miss Sheffield Utd clash through injury
Casemiro was absent from training on Thursday as the team reunited following the international break.
He had played in both Brazil's World Cup qualifiers, playing 79 minutes in their home 1-1 draw against Venezuela before playing the whole game in a 2-0 loss at Uruguay.
"(Casemiro) remained in Brazil, on the club's advice, to recover as swiftly as possible from a small issue picked up while playing for his country," Man Utd said.
The 31-year-old is expected to be back at Carrington early next week to resume training, the club added.
However, Casemiro will also miss the home game against Copenhagen in the Champions League on Tuesday after being sent off in their 3-2 defeat to Galatasaray on October 3rd.
