The 27-year old broke a bone in his foot following a collision with Liverpool midfielder Yossi Benayoun and was seen on the touchline at Anfield with crutches during the second-half. He will now definetly miss United's crucial Premier League game against Chelsea on Sunday, so a start for Darren Fletcher is not out of the equation.
Obviously this is a big blow for United considering Carrick has become an integral part of the United starting eleven. Following his arrival from Tottenham three years ago, Carrick has developed a superb partnership with Paul Scholes in the centre of the United midfield and this could well have a serious affect on the side's form over the next few weeks.
