The Paris-born centre-back will this afternoon lay a wreath at Elland Road in memory of those killed in last week's terror attacks, but will play no part in the subsequent game against Rotherham.
Bamba picked up the injury in last Friday's friendly against Wycombe and Giuseppe Bellusci starts instead of him against the Millers.
Writing about the Paris attacks in the matchday programme, Bamba said: "It hurt me a lot to see so much devastation for so many innocent people in my city. Everybody back home has my full support in the face of what can only be described as an act of evil."
