A RESTRICTED pre-season after a shoulder reconstruction for Western Bulldogs young gun Caleb Daniel means he is yet to join full training.

However, the runner-up in last year's NAB AFL Rising Star to Sydney's Callum Mills told News Corp he was doing most of the work. 

"I've joined in pretty much the bulk of the training – just no contact at the moment. I've started doing weights," Daniel said.

He wasn't the only Bulldog to go under the knife during the off-season, with key defender Kieran Collins also part of the rehab group.

Collins told the club's website he expected to return to training in the next week.

"I did my shoulder against Box Hill in the VFL and had two hip surgeries as well," Collins said.

"I'm coming along alright and feeling fit now. I'm looking to get back into training in the next week or so."

Collins was drafted at No. 26 in 2015 and his mature frame stood out immediately. However, he said his running had improved after losing weight.

"I came to the club a bit heavier than what I would have liked," Collins said.

"I had to lean up and put that muscle on and drop the fat. I have dropped a few kilos since I started."

He was listed at 100kg last year.
