Heynckes awaiting news on Muller injury
Bayern Munich coach Jupp Heynckes hopes Thomas Muller's injury is no more than cramp after the forward lasted just 10 minutes of his side's 1-0 win at Hamburg. Muller came on as a second-half substitute, replacing James Rodriguez, but had to be withdrawn soon after with Heynckes sending Thiago Alcantara on for the Germany star. When asked why he took Muller off, Heynckes told Sky Germany: "He had a cramp. I hope it's only that. We have to wait until the check-up tomorrow."

Balogun suffers injury
Leon Balogun was injured in Mainz 2-0 defeat to Schalke on Friday in the German Bundesliga encounter.

Bernat resumes training
Bayern Munich left-back Juan Bernat returned to individual training on Friday, three months after undergoing ankle surgery.

Bayern have not put a timescale on his return to first-team action, however.
Kruse returns to training
Werder Bremen striker Max Kruse has returned to training for the first time since breaking his collarbone over five weeks ago. The 29-year-old suffered the injury after landing awkwardly following a challenge with Schalke defender Thilo Kehrer on Matchday 4.

Defensive problems for Dortmund
In addition to midfilders Andre Schurrle, Marco Reus and Sebastian Rode, cocah Peter Bosz is also without four defensive players for the Bundesliga clash with Eintracht Frankfurt, Lukasz Piszczek, Raphael Guerreiro, Erik Durm and Sokratis. There are also question marks surrounding the involvement of Omer Toprak, who suffered a thigh strain in the Champions League clash in Nicosia, and captain Marcel Schmelzer, who only made his comeback on Tuesday following two five-week spells on the sidelines with injury.
Martinez suffers shoulder injury
Bayern have confirmed that midfielder Javi Martinez has suffered an injury to his right shoulder joint, but the Bundesliga champions stopped short of putting a timescale on his return. Restored to holding midfield in the first game under Jupp Heynckes, Martinez was one of star performers in the 5-0 win over Freiburg before landing heavily on his right shoulder in the second half.
The Spaniard received treatment on the pitch before attempting to continue, but was substituted in the 70th minute. Bayern have announced that the 29-year-old will be treated by the club's medical staff, but it will not require surgery and he will undergo a rehabilitation plan as well as individual training.
Ribery eyeing early return
Bayern Munich winger Franck Ribery has suggested he may return from injury before the Bundesliga winter break. The Frenchman tore the lateral collateral ligament in his left knee on October 1 and was expected to be out of action until 2018. The 34-year-old, however, says he is in good shape and could well return before Bayern's final game prior to the mid-season break, against Stuttgart on December 16.

Heynckes, 72, has coached Bayern three times before, most recently in 2013 when the side won the Champions League, Bundesliga and German Cup treble.
McKennie to miss Schalke match
