Celtic have had very little choice back to pick Edouard of late, with the striker not getting a break.
Edouard’s form has suffered as a result of his prolonged run in Celtic’s side.
And Rodgers admits that the Bhoys simply must sign a striker in January to take the burden off Edouard’s shoulders.
"I think it is unfair on Odsonne, he's had to play in so many games," Rodgers said.
"As a 20-year-old I would have loved to have taken him out but, because of necessity, he has had to play.
"It is unfortunate for him he hasn't had the support around him to absorb that but it is certainly something we need to look at in January.
"When we had Leigh and Odsonne we were definitely in the market for another one, because of the number of games we play.”
Edouard was in particularly poor form in Celtic’s last match, as they lost to Hibernian at the weekend.
The Frenchman rarely threatened Hibs’ defence, as Celtic crashed to a 2-0 defeat.
The Bhoys don’t have another senior forward currently available to them, so Edouard may be forced to play through his poor form.
Celtic are next in action on Wednesday against Motherwell, when Edouard may be required to start again.
