AC Milan midfielder Kevin-Prince Boateng is a major doubt for the club’s trip to BATE on Tuesday, Tuttomercato reports.The Ghana international is currently nursing a knee injury he picked up in the club’s 3-2 victory at Roma on Saturday, in which he was sent off after having already been substituted.It is still unknown whether Boateng will be able to recover in time for the match, but the feeling in Milan is that he will be spared the trip to Belarus.Italian sources also claim that Philippe Mexes, with a hand fracture, and Clarence Seedorf, still working to regain full fitness, will not take part in the match.AC Milan sit second in the Champions League Group H on seven points, while BATE are fourth, with just one point.The two clubs locked horns earlier in the month at San Siro, with the home side claiming a 2-0 victory with goals from Boateng and Zlatan Ibrahimovic.
