Defender Ritchie De Laet is out, as Leicester City go for four in a row
Defender Ritchie De Laet is likely to miss Leicester City's trip to face Huddersfield tonight.
The right-back limped off in the first half of Saturday's excellent victory at Middlesbrough with a hamstring problem, but Pearson said it may not be a serious injury.
However, he added he was unlikely to risk De Laet at the John Smith's Stadium. Liam Moore is expected to deputise.
"He will probably miss out," said Pearson.

"We will scan him to be sure but he is much better.
"Hopefully, we have caught it before it has developed into anything too serious, but he is in good spirits."
Pearson has no other injury worries as City look to build on their recent good form, but he is expecting a tough test from former City captain Simon Grayson's side.
"They are a decent side," said Pearson. "They have some experience in the ranks, especially at centre-back, two players I know well (Anthony Gerrard and Peter Clarke).
"Depending on fitness, and I know there are one or two concerns up front, they have got some good energy.
"I think they have shown as a team they are a hard-working unit and we have to make sure we impose ourselves on them.
"Their defeat on Saturday is another illustration of the competitiveness of this league.
"They have been in good form and had a good start to the season.
"It will be a tough game but they will be thinking the same about us."
Pearson said Grayson has done a "great job", not only getting the Terriers back into the Championship, but masterminding their impressive start to the campaign.
"It is no surprise to me that Simon has gone into management and is doing well," Pearson added.
"He's done well wherever he has been.
"His thoughts will be the same as mine in that we just want our teams to play well. It is not about the managers, it is about the teams. I think they will be an organised side.
"They are at home so the onus is on them but we go there with a bit of confidence after Saturday."
