Injured Pogba ruled out of Manchester United's trip to Boro

REUTERS - Manchester United midfielder Paul Pogba will miss Sunday's Premier League trip to Middlesbrough with a hamstring injury, manager Jose Mourinho has said.

Pogba was replaced by midfielder Marouane Fellaini two minutes into the second half of United's 1-0 win over Rostov in the Europa League on Thursday.

The French international is also ruled out of the World Cup qualifier against Luxembourg on March 25, followed by a home friendly against Spain three days later.

"I don't know how long (Pogba will be out) for sure," Mourinho told British media. "But there will be no Middlesbrough and no national team."

Defender Daley Blind also left the pitch after a bump on his head and is doubtful for the next game.

Seventh-placed United will also be without suspended striker Zlatan Ibrahimovic and midfielder Ander Herrera for their trip to the Riverside.

Middlesbrough, who are second-bottom of the standings and without a win in 10 matches, sacked manager Aitor Karanka on Thursday. [nL3N1GT45L]
