Brighton manager Graham Potter said he "can't defend" Florin Andone's challenge which resulted in the Romanian's dismissal in the Seagulls' 2-0 defeat to Southampton.
"It didn't look like a great tackle," Potter told Match of the Day. "That's not a tackle we want to see. I don't think he's meant to do it, but it's one we can't defend.
"We tried to be positive with 10 men, but it was a tough task against a good Southampton team.
"We're at the start of this process together. It's about how we react to these moments and situations."
