West Bromwich Albion boss Tony Pulis was baffled by Claudio Yacob's dismissal in their FA Cup defeat to Aston Villa.

Yacob was sent off for the Baggies for a challenge with Leandro Bacuna. Villa's Jack Grealish was also dismissed in injury time after collecting a second yellow card for diving.

Pulis said: "That's (Yacob) not a sending off.

"Yac has had three touches before he blows up. I thought the linesman had said something but I have spoken to Anthony (Taylor, referee) and he has made the decision.

"I don't know what Grealish got sent off for, I was amazed when he showed him the red card."
