The striker has made three appearances for the Championship side since joining on loan.
The Northern Irishman has played three times for the Blues since completing his loan switch from Norwich City. And despite hosting the automatic promotion chasers on Saturday, Rowett suggested that he may look to give the 28-year-old a rest for the game.
"I almost left Kyle out on Tuesday, he felt really stiff after his two games," he told the Mail.
"He obviously hasn't played a lot of football, he hasn't trained that much and we had to limit his training.
"I think he only trained for half an hour on Monday to get through Tuesday's game.
"At some point that might be something we have to look at whether he will get through all the last games or whether we might have to manage that a tiny bit."
The news that Lafferty could be left out at St Andrew's will be a boost to Sean Dyche's men as they look to strengthen their chances of securing the Championship title.
Although the former Rangers forward was unable to prevent his current side falling to a 2-1 defeat to Leeds on Tuesday, he did manage to get onto the scoresheet on his debut so would have surely been one of the players that the Clarets were concerned about.
And while some Blues fans may be annoyed about the prospect of Lafferty being rested while their play-off hopes still have some life left in them, the defeat to the Whites in midweek left them nine points adrift with only five games left.
Therefore, Rowett may be turning his attention to next season by giving the striker time to recover to give him the best chance of playing his best football before the season reaches its climax so he can make a more informed decision regarding to try and sign him permanently.
