Simons' season is now over after suffering a knee injury. Reports suggest it could be an ACL setback, meaning the midfielder won't be seen until the final months of the year - at the earliest.
Simons posted to social media last night: "They say life can be cruel and today it feels that way.
"My season has come to an abrupt end and I'm just trying to process it. Honestly, I'm heartbroken. None of it makes sense.
"All I've wanted to do is fight for my team and now the ability to do that has been snatched away from me … along with the World Cup.
"Representing my country this summer … just gone. It'll take time to find peace with this, but I'll continue to be the best team-mate I can be. I have no doubt that together we'll win this fight.
"I'll walk this path now, guided by faith, with strength, with resilience, with belief, as I count down the days to getting back out there.
"Be patient with me."
