Former Rangers captain Barry Ferguson's season is over after he injured his calf in a reserve game, the Scottish Premier League club said on Wednesday. The midfielder, who was banned for life from playing for Scotland earlier this month, has a small tear in his right calf and will be out for four to six weeks the club said on its website. Ferguson and team mate Allan McGregor indulged in a drinking session after Scotland's 3-0 by the Netherlands and then made insulting gestures while on the bench against Iceland. Both players were told they would not play for the national side again. Ferguson was also stripped of the club captaincy and suspended for two weeks by the club and has not played for Rangers since the incident. Rangers are one point behind Celtic and have five matches left to play.
