French defender Kenny Gillet could make his Inverness debut against Real Valladolid to help ease a potential defensive crisis.
The 24-year-old left-back, who signed for Caley Thistle last week, was not included in the squad which defeated Queen's Park 3-0 in the first round of the Co-operative Insurance Cupbut may be put straight into the first team on Tuesday night after Grant Munro and Chris Innes both suffered injuries.
Munro was replaced by Innes at half-time due to a foot problem, but Innes lasted only 14 minutes before sustaining a groin injury.
Caley Thistle manager Terry Butcher revealed both were doubtful for midweek and acknowledged Gillet, who played most of last season at centre-back for Barnet, would be no stranger to the role if selected alongside Ross Tokely.
"It's disappointing that we picked up some injuries," Butcher said. "Chris Innes had a fantastic 14 minutes, but he pulled his groin muscle so that's very disappointing.
"It happened when he chested it down and passed it to Golly [Stuart Golabek], when a normal centre-half would have smashed it down the pitch and not got the injury. Grant Munro has had four stitches on the top of his foot from a challenge in the first half so that's disappointing as well."
