CARLTON coach Brett Ratten is convinced his team is showing enough promise that it will turn things around and salvage its season.

The Blues have lost their past four matches, with the latest defeat a 50-point thrashing by Hawthorn at the MCG on Friday night.

The loss was Carlton's sixth in seven games since starting the season 5-1, but Ratten said after the match that there were indications the team was on the way to arresting its form slump.

"It might take another week, it might take two weeks," Ratten said.

"I don't know when it's coming, but there has been signs to show in the last three weeks that we can do some good things in games, but our inconsistency in the games is really hurting us."

Carlton finds itself in the congestion that is the middle of the ladder, but Ratten said there was no reason to give up on any hopes of playing in the finals.

"Until you get the calculator and it says we can't, we will not be stopping in our pursuit to do that," Ratten said.

"It's about winning games of football and it's what we're here to do. We'll keep pushing on, whether we can make finals, can't make finals, whatever it is, we'll make sure we're out there to get the four points."

After losing Lachlan Henderson with a groin injury in the lead-up to the Hawthorn match, the Blues' defensive stocks took another battering with a right shoulder injury to Michael Jamison.

Jamison will undergo scans on Saturday, while Henderson will miss at least three weeks.

The injuries come ahead of next week's clash with ladder-leaders Collingwood, but Ratten said the chance to take on a traditional rival could be just what his team needs to snap its losing streak.

"They're in good form and they are playing well. You would think the rivalry would stimulate them and get them motivated. We're disappointed at the moment but we'll reflect, review and we'll push on," he said.

"It's an uncompromising game. If you're in the spot we're in at the moment, not winning games of football, you've got to keep whacking away and working a bit harder. We can't shy away from that."
