Pompey have completed the signing of experienced defender Michael Morrison.
The 34-year-old centre-back has put pen to paper on a one-year deal after leaving Reading at the end of last season.
Blues boss Danny Cowley said: “We’re delighted to sign Michael, who brings a wealth of experience to our squad.
“He’s a fantastic character and will be able to offer great support to the younger members of our group.
“Michael has been a captain pretty much everywhere that he’s been and brings leadership qualities that will help drive our standards on and off the pitch.
"He’s a fantastic character and will be able to offer great support to the younger members of our group."
“He’s been very successful in the Championship and has played regularly in that division over the past few years.
“He can sense danger and has got an excellent ability to read play, while he loves to defend and his organisational skills are great.”
Morrison spent three years at Reading, making 113 appearances for the Championship outfit – with 29 of them coming last season.
He has played in the second tier for Leicester, Charlton and Birmingham, while also winning the League One title with the two former clubs.
Morrison – who began his career with Cambridge – scored for the Foxes when they won a League Cup tie at Fratton Park in September 2010.
In 2011 he had a brief spell with Sheffield Wednesday, where Pompey begin their latest League One campaign on Saturday.
