Amos wasn’t in our matchday squad for the trip to Tynecastle midweek, whilst Moriah-Welsh looked to pick up a knock.
Montgomery discussed their fitness ahead of this weekend.
“Unfortunately, Luke overstretched in the Dundee game, so he’ll be missing for a couple of weeks. It’s tough news for Luke because everyone was starting to see what a top player he is. Fingers crossed it won’t be too long.
“Nectar Triantis can play as a six as well so that gives us another option, but yeah, it’s disappointing for Luke. I’m sure he will be fighting to get fit as quickly as he can.

“Nath (Moriah-Welsh) covered every blade of grass; I think he was fatigued and took a knock on his ankle. He’s ok and has recovered.
“Jake Doyle-Hayes will be back in training soon and Chris Cadden is in full training as well.
“The staff worked really hard to make sure everyone’s recovered and now we’re all champing at the bit for the game against Ross County. The squad is in a really good place.”
