Partick Thistle have signed Gary Fraser on a two-and-a-half-year deal.
The 19-year-old midfielder completed a loan spell from Bolton Wanderers four days ago, although he only played four games after being banned for attacking Dunfermline's Chris Kane in an Under-20 fixture.
He has now returned to Maryhill and could feature against Ross County on Saturday.
Fraser - a former Celtic trainee - moved to the Reebok Stadium from Hamilton Academical on a free transfer in June of last year and was immediately loaned to the Scottish First Division side.
