St Mirren have bolstered their attacking options ahead of the new campaign after signing Paul McGowan.
The Celtic youngster, who spent time with Hamilton last term, joins the Buddies on a season-long loan.
It is the third loan spell the 22-year-old will undertake after spending the 2006/07 campaign with Greenock Morton.
McGowan scored one goal for Celtic last season, a last-gasp equaliser in a 3-3 Europa League draw with Rapid Vienna.
He follows Scott Cuthbert and Graham Carey as Celtic players who also had loan spells with St Mirren in recent seasons.
