Steve Lomas is preparing to enter the January transfer market to resolve St Johnstone's player shortage.
The Saints boss revealed he was down to 14 fit first-team players ahead of their 2-0 defeat by Celtic - their third home loss in eight days.
"We were down to 14 seniors, so it's been a tough week, and we'll have to see if we're getting some back in the not too distant future," said Lomas.
"If not, we'll have to see what we can get in."
St Johnstone's problems were compounded by the loss of David Robertson, who went off injured before half-time following a clash of heads with Celtic defender Daniel Majstorovic.
The former Dundee United man has suspected concussion, but his loss could be compensated by the return of fellow midfielder Jody Morris ahead of the Christmas Eve fixture away to Dunfermline Athletic.
"Jody's trained in the last couple of days," said Lomas of the former Chelsea player.
"So hopefully he'll get a week's training and we'll see where we're at."
Saints' recent poor run has coincided with the loss through injury of strike duo Francisco Sandaza and Cillian Sheridan, but Lomas praised Marcus Haber for his lone role up front against Celtic.
"We would love those boys back as quick as possible," the manager told BBC Scotland.
"It is a problem, but I think big Haber showed what he's all about."
Celtic opened the scoring after the break after Gary Hooper pounced following a corner, then Ki Sung-Yeung finished off on the break after a free-kick from Saints' Liam Craig had been charged down by Beram Kayal.
Lomas praised his players for their performance against second-top Celtic, despite suffering a third straight home defeat that leaves the club eight points adrift of third-placed Motherwell.
"I'm proud of the lads really," he said. "It has been a tough week and they went out and gave another performance.
"They pushed Celtic all the way. The killer was the second goal on our set-piece, where I thought the guy who was booked for charging it down wasn't very far from the ball before he hit it again.
"We got to half-time at 0-0 and I thought were were pretty comfortable apart from Peter Enckelman making a great save to be fair to them.
"Goals change games and they got one from a set-piece, which was disappointing, but I think the killer was the goal from our set-piece.
"I am very proud at the way we kept at it, at 2-0 even."
