Allan McGregor became the third oldest player to feature in 135 years of Old Firm history this week and is on course to break the all-time record if he plays in the remaining games between Rangers and Celtic this season.
The veteran Ibrox keeper turns 41 later this month and helped Rangers to a point in a pulsating 2-2 draw at Ibrox in the traditional New Year's fixture.
Only Rangers' David Weir in 2011 and Celtic's Alex McNair in 1925 have been older than the former Scotland keeper in Old Firm fixtures.
