Jamie Vardy limped off with a worrying hamstring injury that marred Leicester's 4-1 hammering of West Ham at the King Power Stadium.
Ayoze Perez scored twice as the Foxes ended their winless run in the Premier League in emphatic style, but the loss of Vardy with what looked a hamstring injury will be a huge worry.
Vardy limped off just before half-time at the King Power Stadium with his side 1-0 ahead thanks to Harvey Barnes' 24th-minute opener, with the winger then setting up Ricardo Pereira to fire home the second in added time.
West Ham were given a route back into the match five minutes after the interval when Wilfred Ndidi was adjudged to have bundled Sebastien Haller over in the area and Mark Noble scored from the penalty spot.

However, the home side were given a debatable penalty of their own when Kelechi Iheanacho was deemed to have been brought down by Angelo Ogbonna and Perez made no mistake from 12 yards.
The former Newcastle player then swept home his side's final goal of the night to lift them back with three points of second-placed Manchester City. West Ham remain outside the relegation places on goal difference.
