A terrible challenge from Grimsby defender Ben Chapman saw Morrison suffer a Compound frracture of both his tibia and fibia in his left leg, which saw bone sticking out of his skin.
As it was a compound injury, he suffered from infection and complications and had to undergo a total of six operations.
"He's worked ever so hard," explained club physio Nigel Adkins exclusively to Iron-Bru.net, "it hasn't been healing, it's wanted to heal but it hasn't done so properly."
The injury has had a profound effect on the player, and Adkins feels that the battle against adversity has made Morrison a better person.
In recent months his wages have been met by the PFA, and they are likely to help him form a career away from the pitch.
He made a total of twelve starts for the club, as well as a further twelve as substitute.
It is a sad day when one's career is taken away over such an event, Iron-Bru.net would like to wish Peter all the best for the future.
