Ince had to watch from a distance again on Saturday due to his five-match stadium ban, as son Tom inspired the Seasiders to come from behind and draw 1-1 with Birmingham City.
He is worried about the lack of options at his disposal and is anticipating a busy few days as he aims to bring in reinforcements.
"We are massively stretched," said Ince, who will be back in the dugout for next weekend's clash against Sheffield Wednesday.
"We need to try and get some players in before the window closes.
"Ideally we want two players for each position and we haven't got that at the moment."
The manager's absence meant it was left to assistant Alex Rae to fend off questions after the match about the future of Tom Ince.
The England Under 21 international is expected to again attract interest from Premier League clubs in the January transfer window.
Rae said: "He has said he will be with the club until the summer."
