Rangers' first-ever set-piece specialist coach, Scott Fry, is set to leave Ibrox.
Fry, who joined the club from Lincoln City in November, was credited with improving Rangers' effectiveness from dead-ball situations.
However, he will not be part of new manager Derek McInnes' plans for the upcoming season.
It is understood that Fry will return to England to join Birmingham City.
The Englishman, who worked closely with head coach Danny Rohl, was praised for his immediate impact, particularly in creating chances from attacking set-piece situations.
His departure is part of a wider reshaping of the coaching staff at Ibrox this summer.
Fry will join former Celtic coach Chris Davies at St Andrew's.
This comes as Rangers continue to overhaul their staff both on and off the pitch.
Earlier this week, it was revealed that goalkeeper coach Sal Bibbo had signed a deal to join Frank Lampard at Coventry City.
The former Arsenal coach moved to Ibrox last summer as part of Russell Martin's coaching team.

He was reunited with Rohl, having worked together at Sheffield Wednesday, when the German replaced Martin in the dugout in October.
However, he has also now left the club.
New manager McInnes has brought assistants Alan Archibald and Paul Sheerin with him from Hearts, while Craig Clark has arrived from Kilmarnock.
The former Rugby Park coach was expected to join McInnes at Tynecastle before he was named as Rohl's successor last week.
Fry's departure means he will not be part of the coaching staff as Rangers prepare for the new campaign.
In terms of player signings, Ben Godfrey became the club's third signing of the summer on Monday.
He completed a loan move from Atalanta, with Rangers reportedly agreeing a fee of around £3.8 million if the deal becomes permanent next summer.
The first team squad was due to travel to Austria for a pre-season camp in early July under Danny Rohl.
While this option remains under consideration, alternative plans are also being explored, which could result in a change of location.
McInnes said: "We’ve got a structure in place now.
"We’ve been liaising with the club over the last week, so we’ve got dates in mind to tick off our games.
"We’re looking at one or two different options, but we’ve not ruled out going to Austria at this stage.
"We’ve got a couple of closed-door games already booked in, and we’ve got the West Ham fixture at Ibrox.
"We think that will probably be the only game at Ibrox before we play Dundee United."
