The striker has made an instant impact since agreeing a six-month loan move from Ross County, with his goal in the Rams-dens Cup win over Raith Rovers his third already for the Jags after a debut double against Hamilton on Irn-Bru First Division duty the previous weekend.
After replacing the injured Kris Doolan at the head of the attack early in the 4-0 Accies triumph, the 31-year-old was handed his first start for Jackie McNamara last Sunday as they booked a semi-final berth in style.
Despite helping County to the Irn-Bru First Division title last season, he was deemed surplus to requirements by boss Derek Adams.
Craig said: "I haven't really thought about the longer term, to be honest. I am just delighted to be given the chance to be playing football regularly again.
"I was disappointed not to be involved with County but I have come to Thistle and I have the opportunity to play football again.
"That is all I am thinking about. I am a Thistle player now and I will do my best for the team while I'm here. It is soul- destroying when you train all week and then don't play.
"You put in the work during the week with the aim of playing on a Saturday and that wasn't happening for me. That is why I have grabbed this opportunity with both hands.
"I was delighted to get the deal done and be given the chance to play again. I did have a couple of options, but when the move to Thistle came up, it was all done and dusted pretty quickly really."
With Thistle setting their sights firmly on promotion to the Scottish Premier League this season, Craig's experience – and goals – could prove vital for the Jags in the months to come.
Craig said: "I wasn't disappointed at all to be coming back to the First Division.
"I am proud of what I achieved with County last year and I have come to a team with promotion ambitions themselves. If I can help them along and play a part in that then I will.
"I am looking forward to it. Last year at County, we got into the habit of winning games and it is a good habit to have.
"When I found out Thistle were interested, I wanted to come here and hopefully I can play a part in keeping their great run going. When you win games, it breeds confidence."
Meanwhile, Jags will be involved in the SFL's first Friday night match of the season when they travel to Hamilton Accies on Friday, November 16, for a 7.45pm kick-off. The game had been scheduled for the following day.
