Friday's goalless World Cup qualifier between the Republic of Ireland and Wales will undoubtedly be remembered for the horrific injury suffered by Seamus Coleman.
Wales defender Neil Taylor was sent off after recklessly launching himself into a flying challenge which left Coleman with a bad broken leg and needing oxygen before being stretchered off.
The right-back took over from all-time leading scorer Robbie Keane as Ireland captain back in September and has been in excellent form for Everton, but he now faces an extended period on the sidelines and a very long road to recovery.

It's almost certain that Coleman will play no further part in the Republic of Ireland's bid to reach the 2018 World Cup in Russia, and he underwent surgery on the injury yesterday morning.
Irish FA release statement on Coleman
The Football Association of Ireland (FAI) Orthopaedic Surgeon, Professor John O'Byrne, and Consultant Orthopaedic Surgeon, Gary O'Toole, have confirmed that Coleman has fractured both his right tibia and fibula.
In a statement released by the FAI, manager Martin O'Neill said: "Seamus suffered a serious leg injury and has undergone surgery.
"He has had an exceptional season with both club and country, and he will be a big loss. But Seamus is so mentally strong that when he has fully recovered he will be as brilliant as before."
John Delaney added: "Seamus has been a terrific captain for his country, and on behalf of the FAI Board and everyone in the Association, I want to send Seamus our very best wishes."
The FAI CEO continued: "We look forward to welcoming Seamus back to the Ireland team following his recovery."
When is Coleman expected to return?
The FAI did not report an expected recovery time, but injuries this severe in nature usually require at least nine months of treatment and rehabilitation.
That means that Coleman is unlikely to feature for either Everton or Ireland until January or February 2018 at the earliest, barring any future complications or setbacks.
