Potter has edged ahead of rival candidate Kevin Walters . An appointment will be made as early as Thursday.
Matt Parish , the early favourite to replace the sacked Tim Sheens , has missed out and will now take up a three-year deal as Ricky Stuart 's assistant at the Parramatta Eels and continue as a member of the New South Wales Origin staff.
Walters and Potter were interviewed by Tigers management last week, as was Parish.
Potter has support at board level and will sign a deal at Concord, probably for two years.
