Midfielder David McTiernan has completed a move to Blyth Spartans.
A club statement read: "Whitby Town recieved an approach from Blyth Spartans, and after fully consulting with Chris Hardy and his management team and agreed, in view of the player's loyalty and long service to the club, to inform him of the approach.
"The midfielder decided that he would like to speak to Blyth, who have offered him a longer deal with better financial rewards, which Whitby Town cannot afford due to our smaller home attendances.
"McTiernan signed terms with the Spartans on Thursday."
