James Rodriguez limped off just before halftime of Bayern Munich's thrashing of Besiktas in the Champions League.
James Rodríguez could be forced to miss a section of the Rückrunde, after the 26-year-old limped off at the end of the first half of Bayern Munich's 5-0 victory over Beşiktaş on Tuesday with a suspected calf injury.
After the game - in which Robert Lewandowski and Thomas Müller scored a brace each - Bayern's veteran manager confirmed that Rodríguez would undergo tests on Wednesday to determine the severity of his injury.
"He felt his calf stiffen up," Jupp Heynckes said, quoted by the Bundesliga's official website. "He’ll be checked over further tomorrow [Wednesday]."
Rodríguez will be sorely missed in Bavaria if he is made to spend any time on the sidelines. After a difficult start to his Bayern career, the Colombian international has found form in recent weeks, contributing two goals and three assists in his last six appearances.
Fans in Bavaria have only just seen Thiago Alcântara return from a long-term injury, while Manuel Neuer is also set to return from his length injury layoff very soon.
The loanee was already unlikely to start Bayern's second leg against the Black Eagles as Bayern Munich are all but through to the UEFA Champions League quarterfinals, and his absence from their Bundesliga squad shouldn't see the Bavarians' 19 point lead at the top of the table overturned.
However, Rodríguez could play an important part of helping the club secure a domestic double and any serious injury sustained on Tuesday could rule him out of Bayern's DFB-Pokal semifinal against Bayer Leverkusen.
