BRENDON Bolton has conceded emotion got the better of him when the Carlton coach appeared to swear at Essendon's Mark Baguley during the Blues' win on Saturday

Leading by 10 points at three-quarter-time, the Blues found themselves on the verge of their first win of the season.

During the final change, Bolton appeared to bark a profanity towards Essendon's Mark Baguley as the teams approached their respective huddles.

"Probably the passion for our playing group got the better of me. I'll learn pretty quickly from that," Bolton told 3AW radio on Sunday.

"I was probably just saying politely to go back to your huddle because I saw an Essendon player amongst ours coming over to the huddle. As I said, I'll learn quickly from that." 

BAN BOLTON, TOO? Kane calls for consistency

With the Blues 0-7 for the first time in their 122-year VFL/AFL history and languishing at the bottom of the table, Bolton admitted there was plenty of passion at the three-quarter time address.

"When you're a senior coach and we’ve got a group that were fighting really hard in the game that was on the line, at the huddle, it's really important that they see the passion in my eyes. 

"It's like we're dealing with the vibe around a footy club; often the players are a reflection of the coach or the coaches.

"There's no doubt we were passionate, the group were passionate, the leaders spoke in that huddle… I'm glad they fought it out because early in that last quarter Essendon kicked the first couple and we could have crumbled, but we dug deep so that's pleasing."

Ed Curnow was instrumental in the Blues' win, the midfielder kicking two goals and amassing 24 touches while keeping Essendon's prime mover Zach Merrett to 16 disposals.

Curnow, though, may find himself in hot water, after he was seen to make contact with umpire Nathan Williamson in the final quarter.

The incident comes just days after Tom Hawkins received a one-match suspension for intentionally making contact with an umpire. 

Gold Coast co-captain Steven May has already been referred directly to the Tribunal after he also made contact with an umpire in the Suns' loss to Melbourne on Saturday evening.

"We'll see how that one unfolds, it's something that we're not permitted to comment on, and it would be premature for me to do so at this stage, but we've got to continue to respect and understand the role that umpires play," Bolton said. 

"What I can say about Ed is he's of strong character… so we'll just see how that one unfolds."
