DORTMUND, Germany — German league leader Borussia Dortmund signed defender Mats Hummels to a one-year contract extension Wednesday ahead of a game which could see the club end Bayern Munich's decade-long title reign.

Hummels' contract with Dortmund was due to end June 30. The 34-year-old Hummels is now contracted until the end of next season.

“I didn’t make the decision easy for myself. There was a long weighing-up process,” Hummels said in a club statement. "Now, at the end of the season, I can say: I’m still really up for another year.”

Hummels has played 37 games for Dortmund this season and has regularly captained the team in place of Marco Reus. A win over Mainz on Saturday would bring Dortmund its first German title since 2012.
