Speaking of the news, Aston said, “It’s great we’ve agreed this new deal with Menzie.
“He’s in good form at the moment on the field and his fitness is getting better and better.
“Yes Menzie might be known for his big hits and drives but he’s a all round performer and a great asset to the squad.
“He’s a character and the fans love him, it’s a big bonus we can announce this ahead of Saturday’s final.”
