The proposed loan deal to take Inverness club captain Stuart Golabek to Second Division Peterhead until the end of the season has collapsed.
Golabek was all set to join up with Peterhead
The 32-year-old left-back has made just two appearances in the SPL this term but Peterhead say the deal is off.
But Blue Toon manager Steve Paterson has signed midfielder Liam Keogh, 23, from his former club.
Keogh will be a part-time player until the end of the season before going full-time in the summer.
Keogh, who started his career with Celtic, made 10 appearances for Caley Thistle this season, scoring once.
