Hoops boss Neil Lennon admitted Commons may struggle to get up for Saturday's home clash with Caley which poses as a vital fixture following the Old Firm disappointment.
"He trained on Monday and Tuesday and he reported at the airport and felt a stiffness in the groin," Lennon said.
"He could be a doubt for Saturday."
Central defender Kelvin Wilson is also in doubt after copping a knock in last night's 2-0 victory.
"He got one down the back of the Achilles so we will have to wait and see," Lennon added.
"He is limping about the dressing room and he could be a doubt for Saturday."
