Letheren was one of a number of players who have been dealing with illness issues ahead of the Christmas period with a decision being made to bring Boyes back as cover for No.1 Ben Killip in the meantime.
Boyes completed a loan switch to Stockton last month after impressing at Pontefract Collieries where he claimed October’s player of the month award.
Boyes starred in the Anchors' recent defeat to league leaders Worksop, where he also saved a penalty, and Hartlepool boss Curle has suggested Boyes will remain at the Suit Direct Stadium in the interim until Letheren is available to return to the match day squad.
“No, not immediately,” Curle told The Mail when asked if Boyes will head straight back out on loan.
“There was an illness in the camp which has affected the goalkeeping department. So we couldn't afford to leave ourselves short.”
Boyes signed a new deal at the Suit Direct Stadium in the summer until the end of the 2022-23 campaign on the back of making his first appearance for the club in a pre-season friendly with Hibernian.
