The former England skipper has not started a game since suffering knee ligament damage during November's clash with Liverpool, but he came off the bench at Stoke last weekend and could start on Sunday.
"I haven't decided if he will play," said Benitez, whose preparations have been hampered slightly by the blanket of snow that covered Chelsea's Cobham base this morning.
"The (training) pitch wasn't in the best condition, so training was a bit different.
"He's been training with the team and has been fine. We will decide (on Saturday) after the training session."
