Inverness Caledonian Thistle manager Craig Brewster has admitted to being frustrated by David Proctor's continuing problems with an ankle injury.
The 24-year-old midfielder has yet to feature for the Highlanders so far this season, having been suspended for the opening two games before suffering renewed injury problems.
Brewster told the Press & Journal: "We don't know what is up with David Proctor's ankle.
"We will have to send him for a second opinion, as he is not making any sort of recovery.
"He's an important player and we want to get him fit and available again soon."
