Puel made a decision to replace the influential Mahrez midway through the half and the 26-year-old's frustration was visible as he exited the pitch during the 1-1 draw on Friday night.
"For the first time no injured players - just Matty James and Huth not available, all the other players are available as we start with games every three days", manager Claude Puel confirmed, according to the Leicester Mercury.
As soon as lower table Premier League sides recognised this, they soon became comfortable sitting deep and looking for a single goal from a set-piece or counter-attack to take them to victory.
"We spoke at training - it is not a problem", Puel told Sky Sports. "It's a good thing when a player is not happy".
UNFORTUNATELY, this game is not being shown live on TV.
"But now it is important to help him to have more consistency [during] the game because he is a valuable player for us".
For Leicester this was vintage Jamie Vardy and Riyad Mahrez while new boy Vicente Iborra was outstanding in their midfield even if they ended up hanging on with Spurs, who missed four clear chances, demanding an injury-time penalty after Danny Rose went down as he shaped to shoot.
In another game, Brighton and Crystal Palace finished goalless.
The game started at a frantic pace, both teams playing at a high tempo in both their pressing and passing as Leicester and Tottenham looked to make positive starts to the game in front of a boisterous crowd at the King Power Stadium. For us it will be crucial to have good concentration and it will be good to see our progress under pressure against a good opponent and a very good pressing opponent.
"I don't know when they can come back into the team", he added. For all of Tottenham's play however, they were heading into the break 2-0 down courtesy of a spectacular Mahrez goal. "It's a good challenge for us".
