Walker is leaving Cappielow as Kean arrives at Morton
Morton have signed former Queen of the South striker Stewart Kean and allowed defender Alex Walker to join Third Division club East Stirlingshire.
Shire coach Jim McInally signed Walker, 26, for Morton from Rangers in 2005.
McInally said: "Given the circumstances we find ourselves in, I thought he would be a player out of our reach.
"But he is a guy who is now trying to make his way in life with a job outside football and he just wants to play again. We're the beneficiaries."
Walker, who had been loaned to Clyde while with Rangers, had been five years at Cappielow but was farmed out to Brechin City last season to regain fitness after an injury.
Meanwhile, Kean becomes Allan Moore's fifth summer signing since becoming Morton manager.
The 27-year-old, who previously played for Ayr United and St Mirren, was released by Queens this summer after two years with Morton's First Division rivals.
He scored eight goals in 33 appearances last season.
Kean was confirmed as a new signing by Morton on Wednesday along with former Dunfermline Athletic midfielder Graeme Holmes, striker Kevin Kelbie, who had been released by Ballymena United, and ex-Airdrie United defender Marc Smyth.
Moore also returned to his former club, Stirling Albion, to sign winger David O'Brien.
