During Villa's 1-0 win, their defender Mings appeared to throw a nasty elbow at Cherries midfielder Alex Scott.
Scott, it was later shown, suffered a fractured jaw, with Mings escaping referee action for the sixth minute clash. However, Villa teammate Jacob Ramsey was sent off late on.
Afterwards, Iraola said: “We've sent Alex to the MRI because he was really feeling it.
“I think it’s a very violent elbow, very violent. Tyrone Mings sees that Alex is coming and it's a very violent one. And also the first 15 minutes with Alex going out a couple of times, we didn't know if he would continue.
“He wanted to continue and the game basically nothing has happened for this 15 minutes. I think the same way, the second yellow of (Jacob) Ramsey. I don't think it's a second yellow.
“It was close to me and in life it didn't look like a second yellow.
“But obviously a red card in the 6th minute or a red card in the 80th minute, the value is very, very different, but we cannot change this.”
