Middlesbrough have been dealt an injury blow with the news that Scott McDonald will be out for up to eight weeks with a knee injury.

The Australian forward had to be withdrawn midway through the second half of the 2-2 draw at Leicester on Wednesday night.

The 28-year-old suffered medial ligament damage after scoring his ninth goal of the season earlier in the game.

"He will be out for six to eight weeks, four to six weeks, take your pick," said Boro boss Tony Mowbray. "He's desperately unhappy and it's another big loss for us."
