Bournemouth midfielder Phillip Billing admits he would have likely been sent off had he not been substituted against Aston Villa.
The Dane narrowly avoided being shown a second yellow card in the 2-0 victory.
Billing told the Daily Echo: "Some decisions I didn't think were fair and obviously I got booked.
"That's probably why I was a bit frustrated in that game, I'm going to admit that.
"I think the gaffer was right to take me off at half-time because I was on the edge of getting sent off.
"I think if I was to stay on, I probably would have (been sent off) because you can discuss if I was lucky to stay on in the first half."
