RAY McKinnon will be unveiled as the new manager of Greenock Morton tomorrow, Sport Times understands. 

The Ladbrokes Championship side have called a press conference to announce the successor to Jim Duffy on Wednesday morning and we understand that the 47-year-old will complete a move to the Cappielow club. 

McKinnon was sacked by United in October after reaching the play-off final during his first season in charge. 

His appointment at Tannadice came on the back of guiding Raith Rovers to fourth place in the Championship during the 2015/16 campaign. 

Duffy's departure from 'Ton was confirmed at the end of April after four years in charge of the club. 

He led Morton to a seventh-placed finish in the second tier this season, nine points adrift of the play-off places.
