"Petr's problem is an issue we've been managing. It's not decided yet whether he'll need anything done," the Chelsea boss told Sky Sports.
"It's something he's been playing with some period now and it's not an issue now.
"If he stays without pain, it's very possible he'll just play on like that.
"If not, the medical department in conjunction with the player will make a decision."
After sitting out of his national side's friendly against Finland, Cech will be raring to go for Chelsea's trip to Loftus Road for their game against Queens Park Rangers.
