Sports stars and celebrities rallied around Conor’s family on Sunday, more than a week after the crash that sent the 18-year-old into a coma.
The wave of attention put the hashtag “#PrayForConor” on Twitter’s trending list of most popular messages in Ireland throughout Sunday and Monday.
Thousands rushed to get behind the Boyle family as they await more key test results this week.
Donegal’s All-Ireland winning footballers Michael Murphy, Paddy McBrearty and Mark McHugh were among the first to publish messages of support for Conor, who is a keen footballer and plays for Annagry club Naomh Muire.
They were joined by a host of other GAA stars, including Kerry footballers Paul Galvin and Darren O’Sullivan, Galway hurler Joe Canning and pundit Joe Brolly.
“Twitter went through the roof,” Conor’s father Hugh told The Irish Post yesterday (Monday).
“The family is overwhelmed by the support we are getting at this difficult time.
“I am getting calls and texts from people all around the world, people I haven’t even heard from in 20 years. And people who don’t even know us have sent Mass cards.”
Support for the family has also spread across the Irish Sea, with Ireland legend Shay Given, rugby player Peter Stringer and Bradford City footballer Carl McHugh asking their followers to pray for Conor.
Similar messages were published by Holly Hagan and Sophie Kasaei, stars of the hit MTV show Geordie Shore, who share more than 1.5 million followers on Twitter.
