WESTERN Bulldogs recruit Jackson Trengove is set to miss up to three weeks with a cracked shoulder blade he sustained in last Sunday's loss to West Coast.

Trengove suffered the injury in the first term in a marking contest, but managed to play out the remainder of the match.

"This contact resulted in a small crack in his shoulder blade," Bulldogs medical services manager Chris Bell told the club's website.

"He got through the game, which was great, but it’s going to need a couple of weeks to heal properly."

Trengove's absence will stretch the club's depth of talls, with Jordan Roughead set to be monitored this week after the ruckman took no part in the final term following a head knock.

"We removed him from the field of play (after the incident) and assessed him. He developed some concussion symptoms and couldn't take any further part in the game," Bell said.

"We're going to work with Jordan this week and work through our concussion protocol to determine his availability later in the week."

It could pave the way for Tom Boyd to be recalled to the line-up despite him struggling in the VFL win over Essendon on Saturday.

Meanwhile, fellow forward Josh Schache is set to miss another week, with scans revealing a low-grade calf injury.

"Josh reported some calf tightness after a training session last week," Bell said.

"Scans confirmed that he does have a low-grade calf injury.

"I expect him to miss this week but we'll work with Josh next week to hopefully bring him back in line to availability."

Premiership forward Tory Dickson booted four goals in the VFL, while defenders Shane Biggs and Lewis Young had 30 and 24 disposals respectively.
