Ghana defender Daniel Amartey featured for Leicester City in their 2-1 defeat to Chelsea on match week four of the Premier League on Saturday.
Amartey lasted the entire duration of the game as the Foxes failed to take advantage of 10-man Blues at Stamford Bridge.
Chelsea had been completely dominant until Gallagher was sent off before the half-hour mark for a second booking in the space of seven first-half minutes.
That allowed Leicester back into the game and they had the ball in the net before the break, but Amartey’s effort was ruled out with Harvey Barnes harshly adjudged to have fouled goalkeeper Edouard Mendy.
Raheem Sterling's deflected effort looped into the top corner to put the hosts in front 67 seconds after the interval before doubling their lead from Reece James’ inviting ball, much to the relief of Conor Gallagher.
Barnes halved the deficit following a neat one-two with Jamie Vardy in the 66th minute of the game.
Vardy twice went close and Ayoze Perez struck the bar as the visitors pressed for a late leveller that never came, meaning Brendan Rodgers’ side have now lost three games in a row since an opening-day draw with Brentford.
Amartey has featured in all four league games for Leicester City this season.
