Nottingham Forest expect to learn on Wednesday whether striker Dexter Blackstock has suffered cruciate ligament damage.
Blackstock was hurt during Saturday's 2-0 victory at Cardiff City, with the 24-year-old having an eventful spell minutes on the pitch as a substitute.
He was introduced on 70 minutes and scored Forest's second goal with six minutes to go before suffering the knee injury before the final whistle.
Forest fear he has damaged ligaments, which could rule the forward out for the rest of the season, and a scan will take place later this week.
The Championship club are currently waiting for the swelling to subside before arranging the examination and expect to have the results on Wednesday.
With David McGoldrick also currently out with a knee injury, Forest boss Billy Davies is weighing up a move into the loan market to boost his attacking options.
"We will look at the loan market and see what we can bring in now, because we are picking up injuries," said Davies. "But we have a number of players ourselves who want to go out on loan to get games.
"With respect, we do not want to be signing somebody ourselves who is just wanting to go out and get a game of football. We do not want to bring players in who are not ready or who are not the right type for us.
"We will have a look at things. We will see what is available and, if the right player is out there, we will try to do something.
"I am making a list of targets with the staff, but nothing has been identified in terms of definite targets."
