Wigan manager Roberto Martinez is hoping to bring in one more player this month but it will not be a centre-back, despite fears Ivan Ramis suffered a cruciate ligament injury on Saturday.
Franco di Santo's thumping effort earned the Latics a deserved 1-1 draw at Fulham, having fallen behind to a superb Giorgos Karagounis strike on a cold afternoon in west London.
However, the gloss was taken off an impressive point by a serious injury suffered by Ramis, who was carried off on a stretcher off towards the end of the game.
Martinez, who has already signed Roger Espinoza and Angelo Henriquez this month, fears his countryman has suffered a cruciate ligament injury but plans to replace him from within.
"We are in the January window and we are still looking for one player," the Spaniard said.
"I don't think we are going to look for a centre-half because we still have Antolin Alcaraz to come back from injury and Roman Golobart has done really well in the cup.
"I think we will have to cope with it internally, but we'll still try to add one more face before the window closes."
There has been talk striker Di Santo could be on his way out as well, with Liverpool supposedly keeping tabs on him.
The Argentina international was particularly impressive at Fulham, capping a fine display with a fierce strike that secured his side a point.
"It was special," Martinez said. "Strikers are always going to be judged on clinical finishes and what they do in front of goal.
"Franco deserves a special mention for the contribution he has given to the team against Fulham.
"To have a striker with the generosity in his work is difficult to find in the modern game and I was very pleased with the way he worked hard for the team.
"Then the way he found the back of the net was a special, special strike and I think it had to be that way with the home goalkeeper's form.
"Franco can, though, be that clinical finisher, with the right, the left and good in the air. He is a special, special striker and I am glad he got the reward for all the hard work he put in."
Wigan may have returned to the north west satisfied, but Fulham were again left scratching their head.
The Whites have struggled at Craven Cottage this season and yesterday's draw stretched their winless home streak to a fourth game, much to the frustration of midfielder Bryan Ruiz.
"I think that we had the better of the first half and they came back and played better than us in the second half, so a draw is probably a fair result," he told the club's official website, www.fulhamfc.com.
"But a draw is not what we want when we are playing in our own house. We want to get more points at the Cottage to improve our league position and maybe we could have won the match.
"In the last minute of extra time I had a chance from a narrow angle, where I came inside and aimed to hit the ball inside the second post but I don't know how Maynor Figueroa kicked the ball off the line.
"It was a very good goal by Karagounis to put us 1-0 ahead and we were happy with the performance at half-time. In the second half Wigan came at us and made it difficult for us to play."
