WEST Coast draftee Clay Hall has been sent for scans on an ankle injury sustained during the club's internal practice match on Saturday morning.
Hall was helped off the field by trainers at Mineral Resources Park after he was hurt in a tackle from Eagles veteran Elliot Yeo.
The 18-year-old midfielder appears set for a stint on the sidelines.
"It is definitely heartbreaking to see because he's been super, super impressive for an 18-year-old around the ball," West Coast defender Jayden Hunt told reporters.
"He's also the last couple of weeks exploded out of stoppage, which is so good to see.
"I know he'll be pretty disappointed, but fingers crossed it's not too bad."
Hall, the son of former Eagles and Geelong forward Derek, was taken with pick No.38 in last year's draft after an impressive draft year playing for Peel Thunder and Western Australia in the under-18 championships.
His setback continues a disastrous run of injuries for West Coast over the last two years, in which they have managed a total of just five wins.
The Eagles' woes have continued into 2024, with Liam Ryan set for a delayed start to the season after undergoing surgery on a hamstring tendon.
Jack Darling and Tim Kelly have also battled hamstring issues, while Dom Sheed is no certainty to be fit to play in round one because of a foot injury.
Injury-riddled Yeo has managed no more than a dozen games in any of the past four seasons, but is fit again and has impressed over summer.
The 30-year-old is on track to feature in round one.
"I've never really seen a 'Yeoy' like that on my team," Hunt said.
"He was a bit injured last year but again he has just been absolutely dominating, so I'm so excited to be alongside him."
West Coast will play Fremantle at Mineral Resources Park on Saturday, February 24 in the first of two pre-season hitouts, before travelling to play Adelaide on Saturday, March 2 in the AFL Community Series.
The Eagles kick off their season in round one against Port Adelaide at Adelaide Oval on Sunday, March 17.
