Karlsruhe defender Marcel Franke had a good excuse for missing the Matchday 12 clash with Bundesliga 2 leaders Darmstadt - he was potentially saving someone's life.
The club were happy to help after Franke had informed them that - having registered as a donor in 2016 - he was told three months ago that doctors might have found a match.
"The probability that I would be the right donor was actually very low," the 29-year-old told the club website. "But three weeks later I got a call to tell me I was the perfect match after all."

Time was of the essence since the donation had to be made in October, and it was decided that Franke - who had started every game this season - would at least sit out the Darmstadt game.
"For us it was very clear that we would definitely help," the centre-back said. "It's a good feeling to hopefully be able to save someone's life. So of course I can miss out on the odd game for that."
The procedure only took three hours, meaning Franke was likely in good shape to watch Phillip Tietz score a late winner for Darmstadt on Saturday.

"Unbelievable," Tietz said after the game of Franke's decision. "You have to say it's very honourable from the player - and also from Karlsruhe to have allowed him to do it."
