Rotherham United new-striker latest and Ben Wiles injury update
Manager Paul Warne, who is looking to add an attacker and a winger to his squad before Thursday's transfer deadline, had hoped to have a deal for a centre-forward wrapped up in time for Saturday's clash with Leeds United.
But the move was held up because the player's club needed him on their bench for their own game.
"It didn't happen before the weekend obviously," said Warne in the aftermath of an unlucky 2-1 loss to Marcelo Bielsa's Championship leaders 2-1 at AESSEAL New York Stadium.
"It was not through lack of effort from either club really. In the end, I spoke to the manager of the other club. He said he needed him for the weekend, that he needed him for his squad.
"It's something we will have to revisit on Monday morning. I don't foresee any more problems but until I physically see the player at my training ground I'll have an air of pessimism around me. I still think I will welcome him into the club next week."
Warne expects there to be departures from New York this week as well as arrivals.
"Anyone who isn't in the 18 wants to go. I understand it," the boss said. "They have to think of themselves. I have to think of the team and the club.
"There might be some outs if I think they suit us. If I think the outs don't suit us, the players have to sit down and shut up really."
Rotherham, away to Millwall this Saturday, are assessing young midfielder Ben Wiles who missed the visit of Leeds after picking up an injury.
"He's got a problem with his heel," Warne confirmed. "He didn't train all week.
"Leeds would have been a good game for Ben. Out of all my midfielders, he's the most mobile and mobility is key against Leeds because they can all play, they can all shift, they can all have it in tight areas.
"It's disappointing he wasn't available because he's been doing really well. I don't honestly know if he will be available for Millwall. I hope he will be."
The trip to the Lions is likely to come too soon for wingers Ryan Williams and Joe Newell who have hamstring and groin issues respectively.
Right-back Billy Jones returned to the side against Leeds in place of Zak Vyner and rued the 86th-minute winner which cost the Millers a deserved draw.
"We have had a few of those this season where we have played well and have not got the result we would have wanted," he said. We were disappointed with the goals we conceded,
"I think, against a really good team, we were unlucky not to get something.
"Leeds are a great team and that is why they are where they are in the table. They keep plugging away and when they get their chances they take them. But our performance warranted us at least getting a point."
