Aberdeen manager Derek McInnes started his playing career at Morton, making over 200 appearances for the Greenock side.
"I am pleased Morton are in the semi-final, that is my club," McInnes told BBC Scotland. "They gave me my start.
"I have huge respect for everyone there, and the work that the chairman and [manager] Jim (Duffy) are doing. I'm delighted they're doing so well.
"It'll be interesting playing against them. Hopefully we will go there in form, hopefully we can keep this killer instinct and winning mentality we have discovered going."
