The Gers assistant manager says there is no reason Kenny Miller should be thinking about ending his career any time soon.
The 36-year-old Scottish striker returned to the Glasgow club in 2014 after two years in MLS with Vancouver Whitecaps, and has shown signs that he still has the quality despite his advancing years.
Miller became the oldest Rangers player ever to score a hat-trick with his treble against Dumbarton in January, and in total he has scored 15 goals in 32 appearances in all competitions this season.
Weir, who himself played on with the Gers until the age of 41 before hanging up his boots and becoming a coach, told the club's official website that Miller's form and continued class means it is entirely up to him when he decides to call it a day.
Miller's assistant manager told rangers.co.uk: "Kenny trains like a demon every single day and he’s the same in the games. He’s full of energy, he’s full of running, and he’s got a lot of football left in him, no doubt about it.
"I think it’s entirely up to Kenny, he’s obviously got a lot of football left in him and, from my experience when you are that age, you don’t look too far ahead. You just look short-term and try and do the right things.
"You try to maximise what you’ve got and try and utilise your strengths. Kenny does that, he’s the consummate professional and he gives himself the best opportunity. So we definitely won’t put limits on it in regards to how long he can play for."
Miller's excellent season in the Scottish Championship has seen him rewarded with an extension to his current deal, meaning that he will play in the country's top flight for the first time in six seasons if the club are promoted.
That seems nothing short of a certainty, with Mark Warburton's side 14 points clear of Falkirk at the top of the table with a game in hand with only eight matches remaining.
Miller, who has also played for Rangers' arch-rivals Celtic as well as English clubs including Wolverhampton Wanderers and Derby County, has scored well over 200 goals in total during his professional career.
