Arsenal's Henrikh Mkhitaryan out for at least two weeks - Arsene Wenger

LONDON -- Arsene Wenger says Henrikh Mkhitaryan will be out for at least two weeks with knee ligament damage, but could be back before the end of the season.

Mkhitaryan was injured in Thursday's 4-1 Europa League quarterfinal first-leg win over CSKA Moscow and a scan on Friday confirmed fears he will face a spell on the sidelines.

"Mkhitaryan has medial knee ligament damage," Wenger said after Sunday's 3-2 win over Southampton, ruling him out of Arsenal's next three matches against CSKA on Thursday, Newcastle on Sunday and West Ham the following weekend.

"He will miss these games for sure. He could still play at the end of the season."

Arsenal hold a commanding lead over CSKA going into the second leg, but Mkhitaryan's absence would be a big blow ahead of a possible semifinal.

The Armenian won the Europa League last season with Manchester United and was instrumental for Arsenal in wins over AC Milan and Ostersunds in the previous two rounds this term.
