Adelaide is keeping its fingers crossed captain Taylor Walker and vice-captain Rory Sloane will be fit to face premiership favourites Greater Western Sydney at Adelaide Oval on Sunday.
Walker is in doubt with a hamstring complaint, while Sloane is working his way back from a fractured eye socket.
"We're extremely hopeful at the moment they will both be right," Crows ruckman Sam Jacobs told reporters on Monday.
"Sloaney has really started to step up his training the last couple of weeks.
"We're pretty confident he will be able to get up, and Tex, we'll wait and see.
"I'm not sure of the full extent of the injury.
"He's doing everything right. He's been out on the track and making sure he's looking after it properly.
"We're pretty hopeful for both of them."
The Crows will make a final decision on Walker and Sloane after their main training session on Thursday.
Walker had a tight hamstring in the team's final game of the JLT Community Series, while Sloane collided with a teammate during a contested drill.
Jacobs will play his 150th AFL game on Sunday against the Giants after starting his career as a rookie with Carlton.
Now an integral part of Adelaide’s line-up, the 202cm Crow never dreamed in the beginning that he would go on to reach such a milestone.
“Absolutely not,” Jacobs said.
“When I came across I’d played 17 games in four seasons at Carlton. It has been nice to string a few good seasons together and be able to play a fair bit of footy.
“It’s important now that I get that consistency and put a good performance forward every week.
“It’s an exciting week, but I’m looking forward to getting into the game and hopefully getting the win in a milestone game.”
Fellow ruckman Reilly O’Brien recommitted to the Club last week and will remain in Crows colours until at least the end of 2019.
Jacobs said he’s enoyed working with the 21-year-old and was confident Adelaide’s ruck stocks were in good shape heading into the future.
“ROB’s been absolutely fantastic this year,” he said.
“I really enjoy working with him closely, along with Paul Hunter. These guys just want to learn and I try and share as much knowledge as I can with them.
“It’s exciting for the Club. I’ve been relied upon in the last few years because we haven’t had much depth there, so it’s great that they’re coming forward.”
Preliminary Finalists last season, the Giants are again expected to be one of the teams to beat in Season 2017.
Jacobs said it was the perfect opportunity for Adelaide to see where it’s at to kick off the new season.
"They're obviously a really well balanced team," Jacobs said.
"They've got real depth in all their lines and it's going to be a great challenge for us and one we look forward to this week.
"I think we've made some really big gains through our midfield with the stuff we've been working on in the pre-season."
