KENNY MILLER has not ruled out the prospect of returning to Rangers for a third spell with his future at Vancouver Whitecaps uncertain.

The striker, who is 34 next month, is under contract with the Major League Soccer franchise until June but the sacking of Martin Rennie, their Scottish head coach, has cast Miller's future involvement at the Canadian club in doubt. The player is back in Scotland during the close season and has been a regular visitor to Rangers' Murray Park to use their facilities after having knee surgery.

With Andy Little likely to be out for several months after fracturing his cheekbone and jaw, Ally McCoist is on the look-out for a striker. Miller, who was at Rangers from 2000 to 2001 and again from 2008 to 2011, could fit the bill if Vancouver decide to let him go but, for now, the player is unsure as to what the future might hold.

"Anything can happen in football," said Miller. "Until talks have taken place, I can't comment on it. But who knows what can come up. I've got a guaranteed contract until June, so as it stands I'll be going back in January. But you don't know if you'll be in the plans of the new manager. I'm just focused on getting this knee fixed."

Miller has enjoyed returning to his former club. "It's been great," he said. "I need somewhere to rehab my knee and Coisty and Kenny [McDowall, assistant manager] have been brand new; they told me to come in and see Stevie Walker, the physio. He's been great and we're making progress. If I get back quickly, hopefully I can do some proper training with the boys.

"I'm scheduled to go back in mid-January, so I've got another couple of months before I have to get my head round that. I need to make sure I'm fit. I've got a contract and I'll be part of the plans until told otherwise."

Miller, though, has revealed he won't renege on his decision to retire from international football, even if he does end up playing in Scotland again. "No, I don't think so," he said. "The same reasons would still be there. By the time the next finals come around in 2016, I'll be 36½. I feel I could still do a job, but factoring in where I'm playing and when the next finals are going to be, I thought it was time."
