The Leicester skipper has missed the last six games with a back injury, but with fellow defender Robert Huth suspended for tonight’s Champions League quarter-final second leg, the Foxes are desperate for the return of their inspirational captain.
“He’s come through three training sessions and a firm decision will be made on the day of the game,” said Foxes boss Craig Shakespeare.
“I’m really pleased with the way he’s progressed so far. My eyes tell me I should be pleased with the way he’s come through.”
Leicester trail 1-0 in the tie after Atletico scored a controversial penalty which was wrongly given for a shove outside the area.

The Foxes’ sports scientist Tom Joel was also charged by UEFA after being sent off for standing inside the Atletico technical area while handing water out to players.
Atletico boss Diego Simeone and his coaching staff were playing up on the touchline in a bid to influence the officials, and Shakespeare has told his players to keep their cool tonight no matter what the provocation.
“I’m not allowed to comment on referees,” he said. “The players have to be smart.
“We can’t worry about the opposition bench. We have to be mindful, be smart and keep our own house in order.

Leicester boss Craig Shakespeare has urged his players to beware Diego Simeone's touchline antics
“The penalty decision is not gnawing away at me. The last thing the players need is me harping on about it. The referee made his decision – albeit the wrong one.
“In terms of us being over-aroused emotionally, we’ve got the right players to keep cool heads.”
Bookmakers have Atletico as favourites to go through to the last four, but Shakespeare added: “My players look sharp and ready to go. The bookies have got it wrong before so let’s hope they’ve got it wrong again.
“We know we start as underdogs but we’re quite comfortable with that. Let’s hope we can earn our supporters a few bob and get through.”
