Iraola confirmed that Smith had suffered a concussion but was alert and able to recall the incident when assessed after the match.
“Now he looks OK, he's fine and he remembers everything. But in the moment I think it was a very hard knock," Iraola said. “And the doctor straight away, it was bleeding a lot. But it was not about the blood, it was about the concussion and it was obviously the decision to make to sub him.
“And I hope, because now that I've seen him, I've been talking to him, I think it's going to be just this, but we'll have to wait.”
