Harlequins head of medical services Andy Reynolds says coming to the aid of a stricken  non-League footballer is all in a day’s work.

Sutton United boss Paul Doswell described the moment of striker Jessy Reindorf’s training ground collapse at Quins’ Surrey Sports Park base  as “scary as hell”.

The French-born Rwanda international was struck down on Tuesday 
afternoon  in scenes that reminded Doswell of Fabrice Muamba’s collapse at Tottenham Hotspur in 2012.

However, after an ECG scan at Southampton General Hospital revealed no 
heart abnormalities and Reindorf made a full recovery, the incident remains “unexplained”.

Doswell said: “Jessy complained of feeling unwell, so he sat out a running session we were doing.

“Next thing we know, he’s collapsed. It was scary as hell.

“He was completely out of it and fitting a little. We screamed for help from the Harlequins medical team, who train nearby, and they gave Jessy oxygen.”

“But they could not find a pulse on the wrist and we feared the worst.”

He added: “The ambulance guys gave him an ECG and it showed a heart problem, but it was not conclusive.

“We were in shock, we were really shaken up.

“When he collapsed, all I could think of was the likes of Fabrice Muamba and Marc-Vivien Foe, it was that scary.”

Reynolds said: “One of the footballers from Sutton United required medical assistance, so I helped out as any medical professional would. 

“I’d like to wish him a speedy recovery .”

Reindorf may be fit for his side’s Conference South clash with Hemel Hempstead Town on Saturday.
