The Hull defender was on the wrong end of a studs-up challenge that earned Fellaini a red card on the final day of the Premier League season.
The big Belgian will serve a three-match ban at the start of next term, while McShane’s future is unclear after he topped a list of players released by relegated City this week.
At least an unsightly gash should have healed by then, according to the Irishman, who accompanied a picture of the injury with a caption reading: “Looks like Edward Scissorhands has just given me a leg massage.”
McShane later posted a message of thanks to Hull’s supporters after news broke of his release.
It read: “It’s been an emotional rollercoaster right to the end. I’ll never forget the way you fans have treated me and I’ll be forever grateful.”
