Sven Ulreich has gone for scans on a damaged a finger after suffering an injury in Bayern Munich's mid-season training camp just nine days before the club return to Bundesliga action.
Ulreich, who has stepped into the Bayern first-team for the injured Manuel Neuer, made 21 appearances in the first half of the season across all competitions, keeping eight clean sheets.
However, the former VfB Stuttgart goalkeeper could now be forced to miss the start of the second half of the season after damaging his right middle finger at the club's training camp in Doha, Qatar.
