The luckless Eagles have suffered yet another injury blow with Jai Culley forced from the ground in the first term after landing awkwardly in a marking contest against Richmond's Nathan Broad.
The young Eagle was taken into the rooms for assessment on his right knee, subsequently replaced by substitute Zane Trew, with fears the 20-year-old has suffered an ACL injury.
"Jai Culley has gone to ground in a contest," the Eagles tweeted.
"He is now being helped off the field by our medical team.
"We will have an update when one becomes available."
Culley has played four games for the Eagles so far this year, earning the Rising Star nomination in Round 6.
The 20-year-old becomes the latest name on the lengthy Eagles injury list, with the club already struggling with their ongoing injury crisis.
