Corentin Tolisso's and Rafinha's injuries suffered at the weekend have led to Bayern Munich chairman Karl-Heinz Rummenigge demanding more player protection.
French World Cup winner Tolisso tore the cruciate ligament in his right knee following a tackle in their 3-1 home win against Bayer Leverkusen and is expected to be out for a few months.
Rafinha is also set for a lengthy spell on the sidelines with damaged ankle ligaments after a stamp on his heel in the same game.
"It can't go on like this or by matchday 10 (in the Bundesliga), we won't be able to put out 11 players," said Rummenigge.
"We don't like the way teams are playing against us and that has to be sorted out somehow.
"In this regard, we must ask the DFB (German FA), and referees, in particular, to protect our players."
"It can't go on like this or by matchday 10, we won't be able to put out 11 players"
Rummenigge believes German teams are deliberately playing dirty in a bid to stop them securing a seventh successive Bundesliga this season.
"It's partly motivated by the public, under the motto: 'stop Bayern Munich by any means' - that's completely unfair," he added.
Bayern will be without Tolisso, Rafinha and Kingsley Coman, who suffered an injury earlier in the season, for their trip to Benfica on Wednesday in the Champions League.
