Bayern Munich are hopeful that the thigh injury suffered by Germany international forward Thomas Muller in the DFB-Pokal win over Paderborn is not too serious.
Muller had to be replaced just past the half-hour mark of the 6-0 Bayern victory on Tuesday evening, with head coach Jupp Heynckes saying that that was precautionary in nature.

He told the club's official website: "Thomas has a bruised thigh, so we'll have to see how the injury develops over the next few days.
"He could have carried on, but was restricted and unable to give his maximum. We'll have to see how things go in the next few days - I hope he'll be fit for Saturday."
Having booked a place in the semi-finals of the German Cup, Bayern return to Bundesliga action on Saturday when they host Schalke at the Allianz Arena.
The Bavarians, who have won their last 11 games in all competitions, are currently 18 points clear at the top of the table, with Schalke one of a host of clubs battling to secure a top-four finish this season.
Following their domestic duties, Bayern have a Champions League last-16 clash with Turkish champions Besiktas to look forward to next week.
Die Roten can be backed at 12121/1 to win the Champions League this season, with Manchester City available at 12121/1 and holders Real Madrid 4/6.
