Bayern's Arjen Robben leaves match vs. Shakhtar with apparent hamstring injury

Uh-oh.

Bayern Munich star Arjen Robben was forced to leave Wednesday's Champions League match against Shakhtar Donetsk after only 19 minutes, coming off with an apparent hamstring injury.

Robben left the contest with his side already up 1-0 and enjoying a numerical advantage following a red card to Oleksandr Kucher - Thomas Muller would convert the penalty from Kucher's foul.

So while Pep Guardiola likely won't need Robben to ensure progression to the quarterfinals, he'll obviously be hoping the Dutchman - who has a history of injury problems - isn't seriously hurt.
