Chris Judd's extended time on the sidelines last season could help him go out with a bang in 2015, his Carlton teammate Michael Jamison says.

Judd played just one of the Blues' first 11 games last year, with pre-season Achilles tendon surgery and a badly strained hamstring in round five casting doubt over his playing future.

But after averaging 22.1 possessions, 10.7 contested possessions and 5.5 clearances a game following his return in round 13, the two-time Brownlow medallist decided to play on in 2015.

Jamison told reporters on Tuesday he thought Judd's truncated 2014 campaign had been a factor in the 31-year-old's impressive start to the pre-season.

"I think a positive to come out of him missing so many games last year is that he is feeling fresh this time of year," Jamison said at Visy Park.

"(The club is) still looking after him, (he's) still just doing a monitored load, but he's as sharp as I've seen him for a few years."

Kreuzer did not play after round one last year following the recurrence of a foot injury that required surgery at the end of 2013.

The versatile tall started 2015 pre-season training on day one and his fitness and form before the Christmas break attracted rave reviews from Blues coach Mick Malthouse.

Jamison says Kreuzer has continued his strong 2015 preparation since returning to the club last week.

"He hasn't taken his foot off the pedal, 'Kreuze'," Jamison says.

"But we've come to expect that of him, even when he is injured he's always working as hard as anyone.

"We're still mindful it's only very early in January, but he's going just as we expect."

Judd and Kreuzer were among a host of Blues who had disrupted pre-seasons last year, something that undoubtedly contributed to Carlton's slow start to 2014.

The Blues look set to enter this season in far better health, with Jamison particularly encouraged by the greater workloads that Sam Docherty and Lachie Henderson have been able to absorb this summer.

Earlier on Tuesday morning, Carlton players and supporters braved wet conditions at Visy Park as the club held an open training session.

After a heavy session on Monday, three groups of about 12 players completed a light workout that consisted mainly of competitive handball drills.

Judd was among a handful of players who did not take part in Tuesday's skills session.
