The England international faces an extended ban due to the charge, and this could affect Leicester’s Premier League title challenge.
The 29-year-old striker remonstrates with referee Jon Moss after being sent off during the Premier League game against West Ham United at home at the weekend.
Vardy was shown two yellow cards at the King Power Stadium on Sunday afternoon, as the Foxes played out a 2-2 draw with West Ham.
The striker was already going to be suspended for the Premier League match against Swansea City at home this coming Sunday evening, and the FA charge means that he could be banned further.
Former Leicester striker Lineker has taken to Twitter to give his strong reaction to the FA’s decision to charge Vardy with improper conduct.
Don't be ridiculous. Perhaps while they're at it they might rescind the first yellow card. https://t.co/sovOVe0o8X— Gary Lineker (@GaryLineker) April 18, 2016
On Vardy, I never condone dissent at decisions, but it happens in every game. You can't just single out one player. Has to be same for all.— Gary Lineker (@GaryLineker) April 18, 2016
Players should be punished for any kind of abuse of referees. Immediate yellow card. Said this for years. If this is the start then great.— Gary Lineker (@GaryLineker) April 18, 2016
Leicester are at the top of the Premier League table at the moment with 73 points from 34 matches, five points clear of second-placed Tottenham Hotspur.
