Fremantle expects to be without small forward Hayden Ballantyne for at least three weeks, after the small forward strained his right hamstring in the fourth quarter of the Dockers’ 82-point over North Melbourne at Optus Stadium.

Meanwhile, the return date for boom recruit Jesse Hogan is still unclear, despite reports the star forward is pushing to play against Gold Coast on Sunday.

“It’s a low-level injury and it should only keep him out for a short period of time,” Fremantle high performance manager Jason Weber said of Ballantyne’s hamstring concern.

“It’s unfortunate for Hayden, he’s trained really well to this point and he put in magnificent effort in the game.”

Hogan is reportedly eager to make his club debut against the Suns at Metricon Stadium this weekend, after sitting out round one to deal with a mental health concern.

Lyon didn’t rule out the star forward’s return, but said the decision surrounding his availability rested with Fremantle’s medical staff.

“He trained last week (and) hopefully he’ll do the two sessions this week. It’s in the hands of all our experts, really, and I’ll be guided as it unfolds during the week,” Lyon told 7NEWS.

“At the end of the day, I haven’t even got to Jesse. It’s about his care, his wellbeing and he’s in the hands of our experts.

“I’m just a football coach and I plan the session and if Jesse’s in there, I’ll coach him like I coach everyone else.”

Ballantyne is expected to be replaced by Brandon Matera, who is eligible to face his former club after serving a one-week suspension for clipping West Coast’s Jake Waterman with an errant elbow during the JLT Community Series.

Second-year small forward Sam Switkowski (hamstring) could be another candidate to fill the veteran’s shoes, provided he passes a fitness test later in the week.

Mobile defender Griffin Logue (hamstring) has progressed well at training, while midfielder Connor Blakely (hamstring tendon) continues to make strides in his recovery.
