Allan Johnston is confident his injury problems are behind him after joining St Mirren for the remainder of the season.
A chronic hamstring injury plagued the 35-year-old's final year at Kilmarnock, although he underwent an operation to cure the problem in April.
The former Middlesbrough and Rangers man had been training with the Buddies in pre-season before putting pen-to-paper on a season-long deal on Tuesday.
Johnston is delighted to have joined St Mirren and is looking forward to helping the club progress, despite conceding there were times when he thought he may have to hang up his playing boots.
"I'm delighted to have signed and hopefully I can work my way into the team," explained Johnston.
"I was injured for most of last season so I had to prove my fitness before signing and I've been able to do that.
"I've been here training with St Mirren for a few weeks and that's been good as I've got to know the boys.
"I had to rest after having the operation but during the summer I saw the Kilmarnock physio and did exercises with him.
"I'm confident all my problems are behind me as I've been training over the past couple of months and everything has been fine.
"There were a few dark moments but I never thought I would have to stop playing.
"I'm delighted to have joined a club which is going places with the new stadium and new training facilities."
Meanwhile, long-term injury victim Chris Smith has expressed his delight at being given the all-clear to resume training.
It had been thought the 23-year-old would spend at least a year on the sidelines when his knee injury was discovered in March.
However, he has made a remarkable recovery from cruciate ligament surgery and is hoping to be back in full training in two weeks.
"I'm really happy about the news; when the surgeon told me I could go ahead with things, I could have flown home from London under my own steam," said Smith.
"Over the next couple of days, I'll be working on goalkeeping stuff like jumping and diving then hopefully in a couple of weeks I'll be back to full training with the rest of the squad.
"I'm just looking forward now to getting back in with all the boys again - it'll get my shoulders back up again to be back in among the rest of the players."
