The 31-year-old former Premier League striker sustained the injury in a regulation tackle from Sun Xiang as his Shanghai Shenhua beat Shanghai SIPG 2-1.
Ba's coach, Gregorio Manzano, suggested that he issue could perhaps force the conclusion of the Senegal international's playing days.
“It could end his professional career," said Shenhua head coach Manzano.
“I would rather lose the game than lose Ba."
Since joining Shanghai in June last year, Ba has amassed 27 goals in 36 appearances with 14 of those coming in 18 matches this season.
