The 25-goal forward, named Sky Bet Championship Player of the Year on Sunday, will see a specialist on Wednesday to assess an ankle ligament problem which forced him to miss just his second game of the season on Saturday.
Ings revealed his ankle was "okay" at the Football League Awards ceremony but the very fact his ligaments appear to be damaged suggests his return may not be forthcoming, with the Clarets due to host top-of-the-table Leicester a week on Saturday.
Sean Dyche's side have a 10-point cushion over third place yet with the Premier League seemingly in touching distance, the Clarets board are willing to back their manager in the loan market if the news on England Under-21 international Ings is bleak.
The loan window closes a week on Thursday and, in quotes reported in the Lancashire Telegraph, Burnley co-chairman John Banaszkiewicz said: "He (Ings) has got a couple of tests in Leeds.
"We hope for a good outcome, but in the interim we have to look for a replacement if it's more serious or worse than expected.
"We are in the market for loans for cover with not many games left to play.
"The manager and recruitment staff are really focusing on that before next week's deadline."
Dyche can still can upon Sam Vokes - who has proved the perfect foil for Ings, scoring 19 goals himself - while January signing Ashley Barnes started his first game in Saturday's 2-1 win over Leeds.
