St Mirren have completed the loan signings of Daniel Finlayson and Brandon Mason on transfer deadline day.

Finlayson, 19, joins on a season-long switch from Rangers, with the option to buy the defender at the end of the term for an undisclosed fee.

Mason, a Watford youth academy graduate, also joins on loan for the whole campaign from English Championship side Coventry City.

The left-back's parent club will have the option to recall him in January.

The moves come following the departure of club captain Kyle Magennis to Scottish Premiership rivals Hibernian on Monday afternoon.
