Bayern boss Jupp Heynckes, who earned a record 10th consecutive Champions League win, confirmed that the Colombian was forced to withdraw from the match.
"He felt his calf stiffen up [...] but I don't think it's anything serious," Heynckes said after the game. The 72-year-old's diagnosis was confirmed on Wednesday by club doctor Hans-Wilhelm Müller-Wohlfahrt. A statement on the Bayern website read that James' injury "is not serious" and that "he merely has a minor complaint in his left calf muscle, meaning he will not take part in training for a few days."
Watch: See all of the goals James has scored or made in Germany
James, 26, has been in excellent form since settling into life in Germany. After arriving in Munich over the summer, he has scored four goals and made six more in only 16 Bundesliga appearances.
Described by Heynckes earlier this month as "a godsend" for Bayern, James said last week that the Bundesliga leaders could repeat their treble success of the 2012/13 campaign.
