Birmingham defender Paul Robinson has signed a new one-year contract with the Championship club.
The 34-year-old's new deal also has the option of a further year at St Andrews.
Robinson was initially signed by Blues manager Lee Clark last September on a month-to-month basis in order to provide defensive cover across the back four.
However he produced some impressive performances for City which were rewarded with a contract until the end of last season and that has now been extended.
Robinson, who has previously played for Watford, West Brom, Bolton and Leeds, has made a total of 37 appearances for Birmingham so far.
Morsy was offered an improved two-year deal at the end of the season but he has opted not to sign it.
As he is under the age of 24, any club Morsy signs for will have to agree a compensation package with the Valiants.
Meanwhile, Liam Chilvers has agreed a new contract and the centre-half will put pen to paper before the players return for pre-season training later this month.
Manager Micky Adams continues to negotiate with captain Doug Loft, who was also offered a new deal at the end of the 2012/13 campaign.
Jepson, who played for the Shakers between 1996 and 1998, becomes right-hand man to Kevin Blackwell at Gigg Lane just hours after Shirtliff stepped down having expressed a desire to depart.
Jepson will start his new position with immediate effect as Bury, relegated to League Two, begin the job of rebuilding under new chairman Stewart Day, who only completed a takeover of the financially-stricken outfit at the end of last month.
"It's good to be back, I have some great memories of this place and a lot of success here," Jepson told the club's official website.
"When the gaffer rang me and offered me the job I didn't think twice. We had a quick chat and everything was sorted out quickly and I'm ready to go.
"I know where this club can go and I know Kevin Blackwell is very excited with the new ownership. In terms of the philosophy and where we are going to go, I am now a part of that and really looking forward to it.
"I've met the chairman and the team behind him. This is exciting times for this football club. It's a fresh start with new owners, plus I know Kevin from old. He wants to be successful and he's a driven man, the same as me."
Jepson has previous management experience at Gillingham while he has also held assistant and coaching roles with the likes of Burnley, Huddersfield, Crystal Palace, QPR and Leeds.
