Munich, Germany (SportsNetwork.com) - Bayern Munich's disappointing return from the Bundesliga winter break continued at the Allianz Arena on Tuesday as the club was held to a 1-1 draw by Schalke.

The reigning champions returned to action on Friday and laid a massive egg, suffering a 4-1 loss to second-place Wolfsburg.

It looked to be much of the same in Tuesday's affair as Jerome Boateng was sent off in the 18th minute for denying Schalke a scoring opportunity. Eric Maxim Chupo-Moting could not punish Bayern any further as the Schalke striker failed to convert the ensuing penalty, saving Boateng's blushes.

The hosts eventually took the lead in the 67th minute when Arjen Robben, first to meet a corner kick, sent a glancing header just inside the far post.

The lead was short-lived, though, as Schalke answered five minutes later with a virtually identical goal. It was Benedikt Howedes doing the honors, crashing the penalty area to send a powerful header just past Manuel Neuer at the far post.

Neither side managed to find a winner in the closing stages, leaving first- place Bayern to settle for a home draw and bring its total to 46 points through 19 matches.

The draw ultimately did not hurt Pep Guardiola's men as Wolfsburg was held to a 1-1 draw at Eintracht Frankfurt on Tuesday.

The hosts were in front through Stefan Aigner's 58th-minute goal, but Kevin de Bruyne netted the equalizer two minutes from time to see Wolfsburg salvage a share of the spoils and keep the club within eight points of Bayern.

Also in Tuesday's Bundesliga slate, Patrick Herrmann netted the lone goal in Borussia Monchengladbach's 1-0 home defeat of Freiburg while Elkin Soto scored in the 77th minute to help Mainz to a 1-1 draw at Hannover.
