Milan lost Dida to a freak injury during Saturday's 0-0 draw at Parma when his back froze as he tried to stand up from the bench.

Now the club has released a statement warning that Australian international Kalac is also at risk for the Emirates stadium.

"During today's (yesterday) training session the goalkeeper Kalac dislocated the phalanx of his index finger on his right hand.

"His condition will be evaluated tomorrow to understand if he will be available for the London match against Arsenal."
