The wing duo emerged from their Football Association hearing with monetary punishments for becoming embroiled in the ugly scenes that marred the end of the goalless draw with The Gunners.
"I haven't spoken to Maurice Watkins about it yet, I had to leave before the end to come back to Manchester," explained Ferguson.
"I wasn't there when the verdict was given, but we're disappointed.
"I'll have to speak to the players and Maurice before I make any further comment."
Meanwhile, Ferguson will continue to utilise his youth policy in the Carling Cup when West Brom provide the opposition in the live Sky fixture on Wednesday evening.
Chris Eagles could be handed a starting role after impressing in the previous round against Leeds United, and Phil Bardsley, son of former Watford defender David, is in line for his first team debut.
"It will be similar to the Leeds United game," Ferguson told United's official website. "All the players who haven't been playing will play.
"(Nicky) Butt, (Eric) Djemba-Djemba, Kleberson, (Darren) Fletcher, (David) Bellion and young players like (Kieran) Richardson and Eagles will be involved.
"I just have to look at the defensive side.
"The reserves have been playing very well recently. Danny Pugh has been doing well and so has young Bardsley. These young lads will get their chance.
"First of all, I want to make sure we have got enough strength going into a game like this.
"Chris Eagles made his debut at Leeds and did exceptionally well. Young Kieran Richardson, Darren Fletcher, David Bellion are all yong players.
"We're very enthusiastic about their chances.
"It's the kind of game you would want them to go into. I think it could be a smashing night for them."
