Lawrence Shankland and Zander Clark, as well as new signing Gerald Taylor, will all be involved for Heart of Midlothian against Tottenham Hotspur.
Hearts host the Premier League side on Wednesday night and fans will be able to see the returning Scotland duo as well as the most recent recruit from Costa Rica.
Shankland and Clark returned to training last week having been given time off due to their involvement with Scotland at Euro 2024. Taylor joined up with the squad for the first time on Monday.
"They'll be involved on Wednesday and then they'll follow the first-team schedule from now on," Steven Naismith confirmed.
He added: "Today is the first day that I've seen them and I've not spoken to them about Scotland at all. It was more about their holidays and if they enjoyed their time off, how do they feel personally.
"There will be disappointment, without a doubt, with the way the campaign went. But there's then a lot to look forward to with us this season, being in Europe, the challenge of bettering what we did last season. They seem to be back to their normal ways in training."
Kenneth Vargas will be the last to return to the squad followed his break after the Copa America. He is due back later this week.

"It's just all down to when their last game was," Naismith explained. "We believe that the players who have been away need time to rest more than fitness. I'm not going to compromise on that.
"He'll be ready for the first game of the season, and hopefully he starts like he finished last season."
Meanwhile, James Penrice won't be involved against Spurs as Hearts continue to ease him back in. The left-back missed the last four months of last season with a hip issue. The new recruit spoke about being cautious when in Tenerife.
"It'll be a week or two before he's back involved in games but that is to make sure he's robust enough," Naismith said. "He's had a stop-start time for the past year and we don't want to risk it for short-term gain. But he's looking really sharp. It's us holding him back."
