ADELAIDE'S first-round draftee Chayce Jones did his chances of a round one debut little harm following an impressive display against Greater Western Sydney on Friday night, according to coach Don Pyke.

Jones, the ninth pick overall in last year's NAB AFL Draft, gathered just nine disposals but thrived in a role as a pressure forward in the Crows' 18-point win in the JLT Community Series in Canberra.

The 19-year-old laid five tackles and kicked two goals, with one of them coming from the goalsquare after a desperate clinging tackle on Giant Adam Tomlinson to cause a turnover.

Jones played limited game time against Port Adelaide in last weekend's clash in Port Pirie, but ran out a full match against GWS.

"He did some really nice things in the pressure stakes. He's a young man coming in and we thought we'd give him an opportunity and see what that looks like for round one," Pyke said.

"He certainly didn't do any harm tonight with some of his efforts around there (the contest). He didn't generate a lot of the ball but he certainly played the role we're looking for.

"He's got a bright future, I think."

The competition for spots for round one against Hawthorn is incredibly tight at the Crows, with usual walk-up starts David Mackay (AC joint) and Hugh Greenwood (abdominal) hoping to press their claims during a SANFL trial match on Friday night.

Myles Poholke and Andy Otten also played in the SANFL trial after being dropped, with Cam Ellis-Yolmen and Darcy Fogarty playing limited game time in the AFL side.

Ruckman Reilly O'Brien didn't even get onto the ground despite being suited up in his playing kit.

"The squad's in a good spot. There's strong internal competition for spots and there's some guys that are pretty stiff to be out of the team," Pyke said. "That's healthy."

WHO MAKES FINALS? Do the 2019 Ladder Predictor

Pyke was pleased with his side's ability to cope with the Giants' initial pressure in the first term, while there were no fresh injuries out of the match.

Meanwhile, GWS assistant coach Matthew Nicks believes Toby Greene will be "better for the run" after he made his long-awaited return from off-season ankle surgery.

Greene played a little more than a half against the Crows as part of his preparation for round one, while Tomlinson also made his return from a calf injury.

"We came into the game with the idea to monitor those guys and keep an eye on some of their loads and we were looking at about a half. Toby ended up playing a little more than that, which was great," Nicks said.

"He'll be better for the run. His touch was slightly off but that's what happens when you haven't played footy for a while."

Nicks said Greene and Tomlinson would play almost a full game in an intraclub hitout next Saturday to prove their fitness for the opening-round clash with Essendon.

Nicks was impressed with forward Daniel Lloyd who booted two goals from 15 disposals.

"He really has (taken his chance)," Nicks said.

"He's been real quality for us. He's taken his workrate and his off-field stuff to another level and there's still a lot of improvement to come.

"It was nice to see him step up and show some stuff through that last quarter especially."

The Giants also got through the game against the Crows unscathed.
