The Kirkhill player was forced to concede his last-32 tie against fellow Scot Liam Johnston at Humewood Golf Club due to illness.
Ross, who’d won his first-round tie 4&2 against Clement Charmasson on Tuesday, was three down at the time after seeing his Dumfries & County opponent get off to a fast start.
“I was up sick all last night and just felt weak and dizzy, as well as sweating a lot, this morning,” said Ross. “I tried to play but just was getting worse on the course.”
Ross and Johnston had been left as the last two Scots standing after Calum Fyfe (Cawder), Jamie Stewart from Old Ranfurly and Peebles player Craig Howie all bowed out in the opening round.
Howie went out at the 22nd hole in a marathon match against home hope Jason Smith.
Scottish players have won the event four times in the last six years.
Gleneagles has been confirmed as an “official supporter” of the Glasgow 2018 European Championships.
The Perthshire venue had already been announced as the venue for the mixed golf tournament that is part of the multi-sport event for the first time.
The event, which is backed by the European Tour and Ladies European Tour, will include a men’s and women’s event along with a ground-breaking mixed competition.
“We’re proud to be associated with what will be a ground-breaking moment in sporting history,” said Bernard Murphy, Gleneagles’ managing director.
“The event will build on Gleneagles’ long history of raising the bar in golf and breaking cultural boundaries in sport – including the first match between British and American professionals in 1921.
“We look forward to continuing that tradition at the European Golf Team Championships, when Europe’s leading men and women compete together for the first time, in what will be a real historic moment for the sport.
“We are therefore delighted to be announced as an official supporter of Glasgow 2018, and look forward to delivering an inspiring event that will strengthen Gleneagles’ reputation as one of the foremost golfing venues in the world.”
