Bayern Munich forward Thomas Müller is likely to be fit for Sunday's big Bundesliga clash with Freiburg despite coming off after just 25 minutes of Wednesday's 4-2 win at Viktoria Plzen.
The victory sealed Bayern's passage to the last 16 but looked to have come at a cost as the Germany man was substituted having scored and made a strong start to the game.
But coach Julian Nagelsmann said he ought to be fine for the visit of Freiburg, who are second in the Bundesliga, two points above third-placed Bayern. Leaders Union Berlin also host fourth-placed Borussia Dortmund on Sunday.
"The muscles closed up a bit in his back. Nothing serious. A bit of a nerve problem," Nagelsmann told DAZN. "It's nothing dramatic, no risk for the weekend."
Müller - who had missed the last two games with coronavirus - did not sound quite as sure as his coach, saying only that "it probably isn't that bad."
Even if fit, Bayern still have a lengthy injury list and the return of goalkeeper Manuel Neuer from a shoulder injury is still uncertain. "He is a little better in terms of pain," added Nagelsmann.
