They were already reeling from the news that No7 Cooper Cronk (broken arm) is gone for the series, out for up to three months after going down in the first 10 minutes of Wednesday night's loss.
Slater suffered a grade-two AC joint sprain to his right shoulder.
The man who will again attempt to fill Cronk's shoes in Origin II, Cherry-Evans, downplayed concerns he would be added to the Maroons' injury list.
"I was a bit worried about it. It just needed a night to settle so I'm hoping it's all right," said Cherry-Evans.
Still, a major Origin II overhaul looms.
Broncos backrower Sam Thaiday (calf) should be fit to return. Brisbane prop Josh McGuire and Gold Coast Titans giant David Taylor may also be called up.
Roosters hooker Jake Friend has already been earmarked as Smith's understudy after being named Queensland's 19th man for game one.
