Oklahoma City Thunder's Anthony Morrow ruled out for up to six weeks

Oklahoma City Thunder guard Anthony Morrow will miss the start of the NBA season due to a MCL sprain.

The 29-year-old sustained the injury during his side's practice session on Thursday and could now be out for up to six weeks.

Morrow is in line to miss 20 of the Thunder's matches at the start of the campaign, and, with a six-week recovery, his return would coincide with his side's home matches against the Milwaukee Bucks and the Cleveland Cavaliers.

The guard joined the Thunder in the off-season from the New Orleans Pelicans.
