Former Dundee Paul Hartley has signed a former Dens Park trialist.
Mark Russell was training with Neil McCann’s side last week with a view to earning a deal with the Premiership side.
However, the left-back didn’t do enough to earn a deal but was quickly snapped up by the Bairns.
The 22-year-old has joined the Championship team on an initial six-month deal.
Russell featured more than 100 times for Morton before leaving at the end of the season.
Paul Hartley said his new recruit “adds further strength” to his squad.
