St Mirren can confirm that Danny Mullen has signed a permanent two-and-a-half-year deal with the club.
The 22 year-old striker joined The Buddies on an emergency loan in December and has now signed with the club for an undisclosed fee.
Speaking on the permanent move, Jack Ross said: "I spoke when he signed the emergency loan about how pleased I was to get him.
"It's been difficult for him because he's been playing catch up a little bit having had the injury, but the contribution he has made in the two games he's started has been brilliant.
"He's still adjusting to how we train and how we play but he's settled in really well and the players like him. I think he'll play a big part for us in the second half of the season."
