The Horsham Demons' luckless run with injury continued on Saturday, with co-coach Deek Roberts sustaining an arm injury.
Roberts was awaiting further results from scans on Tuesday afternoon to determine the extent of the injury.
The two-time Dellar Medalist had his arm caught and twisted under a tackle on Saturday, in Horsham's Wimmera league clash against the Southern Mallee Giants.
"There was nothing in it, it was just unlucky," Roberts said of the incident.
"They said at this stage there's no crack (in the bone), but there's a fair bit of swelling. I'll get the full report from the doctor Monday night.
"It's not feeling great, so I'll probably miss a week and see how it goes. That will be my plan anyway - I'm not sure if the doctor will say, 'that is ridiculous', but we'll have to wait and see."
Roberts' injury comes after Horsham's star full-forward Joshua Mibus (knee) and club stalwart Jordyn Burke (neck) both suffered injuries likely to keep them out for the remainder of the season.
It is also another frustrating blow for Roberts, after he missed the back half of the 2018 season with a broken leg. The injury forced him to coach Horsham's grand final victory against the Southern Mallee Giants from the sidelines.
Roberts said the senior side had faced a difficult run with injury so far this season.
Roberts was hopeful of soon regaining the services of key pillars Sid Hernon and Dawson Cross, who have both been missing with injury for more than a month.
"They are a couple of really important guys," Roberts said.
"It would be nice if we could get all of them out there and injury free, but we'll just have to manage guys at training a bit better, and hopefully get a bit more luck."
While the injuries have certainly hurt the Demons, Roberts said it wasn't an excuse for their disappointing results across the last month.
The Demons are currently in fifth place on the Wimmera league ladder, with just percentage separating them and the sixth-placed Horsham Saints.
Horsham has not missed finals in the Wimmera league since 2001.
"We aren't making excuses - we just haven't been good enough," Roberts said.
"Our season is in our hands at the moment. It's pretty simple, we just need to start winning games.
"We've had our chances the last few weeks - I'm still confident in the back half that we will be in enough games, it's just about stringing four quarters together."
