Dumbarton manager Stephen Aitken has added two more players to his squad ahead of Friday's Ladbrokes Championship game away to Falkirk.
Former Stranraer and Kilmarnock defender Frazer Wright makes the move to the Cheaper Insurance Direct Stadium after leaving St Johnstone and ex-Ross County forward Steven Ross has signed a deal until January.
Aitken told the club website: "Frazer is someone we looked at when we first came to the club so when the chance to get him came after his St Johnstone release we had to follow it up.
"Stevie has been on our radar for some time and we have now managed to get his deal over the line. He's a big lad and has pace, so we'll have further options up front."
