It was tight and certainly not faultless, but Carlton has now won seven wins on the trot after the club's two-point victory over Richmond on Saturday.

The Blues scraped over the line without key defensive pillars Jacob Weitering (calf) and Harry Dean (hand), while Lewis Young was removed from the game after being concussed in the third quarter.

Carlton interim coach Josh Fraser said he expects his 18-year-old star to return to the line up next week after he suffered an unusual injury.

"We anticipate (Dean) will be fine," Fraser said in the post-game press conference.

"I'm not 100 per cent sure (how he cut his hand). I'd like him to stay away from sharp objects for a little while. He has become pretty important to us.

"He has great character, I referenced being a Carlton person, like he looks like a Carlton footballer when he plays footy. He will be available next week.

"I haven't had a recent update other than I knew (Young) was taken out of the game because of concussion, which put a little bit of stress on us in terms of having to move (Mitch) McGovern back and a few other moving pieces.

"I'll get an update on him probably tomorrow, but hoping he recovers well."

The Blues led the game by 14 points with just under two minutes left, before a controversial decision to call a deliberate rush behind on Carlton defender Nick Haynes cut the margin back to eight.

Haynes, while not under direct pressure from Richmond players, did walk over his behind line with Tigers players near him and had opportunities to keep the ball live.

Speaking after the game, Haynes ran through his thought process on the decision.

"I think if I took it over the first time I would have been sweet," Haynes said to AAP.

"I think that hesitation, just not taking it over put a bit of less pressure on me, so therefore they paid it.

"It could have gone either way, but I think I should have rushed it over that first time and then we wouldn't even be talking about it, so probably my fault."
