Welsh midfielder Ryan Giggs could be Manchester United's injury doubt for the English Premiership team's Champions League away match to CSKA Moscow on Wednesday. "Ryan Giggs has got a knock and is a doubt for Wednesday," said United manager Alex Ferguson.
The veteran had been knocked down during Saturday's 2-1 win over Bolton and is unlikely to travel to the Luzhniki Stadium at the Russian capital.
Other key players might miss the Moscow showcase include Patrice Evra, Dimitar Berbatov, Wayne Rooney and Nemanja Vidic.
United top Group B with full points from two games, while CSKA have won one and lost one.
