INDIANAPOLIS As if UConns challenge wasnt daunting enough facing formidable Michigan, now the Huskies could be without a key player for Monday nights national title game.Junior guard Solo Ball, the teams third-leading scorer this season, has some kind of foot sprain that he sustained early in Saturdays 61-52 victory over Illinois, UConn coach Dan Hurley said Sunday. Ball is wearing a walking boot and will not practice Sunday with the rest of the Huskies.When asked if Ball is likely to play against Michigan, Hurley said, I dont really know.Well know more as it gets later in the day, he added.Ball has started all 38 games for UConn so far this season and has averaged 12.9 points and 3.1 rebounds. Ball was able to finish Saturdays national semifinal against Illinois despite his injury, tallying 13 points and knocking down a trio of 3-pointers.If Ball is unable to play or is hampered by his injury, it would likely mean more playing time for reserve guards Malachi Smith and Jayden Ross. Ross has come up big off the bench twice in the NCAA tournament, scoring 11 points against UCLA and sinking a pair of threes against Illinois.
