St Mirren is pleased to confirm that Calum Waters will remain at the club until the end of the season.
The left-back joined Saints on a loan from fellow Ladbrokes Premiership side Kilmarnock in August.
While it was a season-long loan that Calum signed, Kilmarnock retained the option to recall him in January.
However, it has been agreed that Calum, who has made 18 appearances so far for the Buddies, will remain in Paisley until the end of the season.
