According to the Daily Record, former Hoops captain McNamara has undergone emergency surgery after collapsing at home following a bleed on the brain, and continues to recover in hospital.
The 46-year-old is one of the few footballers who won respect from supporters on both sides of the Old Firm divide during his playing days thanks to his lung-bursting runs and committed displays, and news of his illness has left fans deeply upset.
McNamara’s former Celtic team-mate Larsson and Rangers idol McCoist have both taken to Instagram to wish their pal all the best, whilst Jackie’s daughter provided a family update via social media:
As well as winning 33 caps for Scotland, McNamara won four Premiership titles during his time at Parkhead, including the 1998 title which crucially stopped Rangers from winning 10-in-a-row.
Get well soon, Jackie.
