Wow - a bit of an overstatement.
I understand and agree with the empathy, but he no more put his life on the line than any other player in the team. In fact, no more so than any other footballer in any team at any level in the country. It's a contact sport and everyone playing it is at risk of serious injury. But "literally put his life on the line"?
If he was somehow aware before the game that he would suffer life-threatening injuries and still decided to play - then yes, he would have literally put his life on the line.
