The 23-year-old kept a clean sheet in the 0-0 draw at Slovacko, which was enough to confirm a record-extending 37th top-flight crown for Sparta.
Kovar and his fellow Reds are three points ahead of Slavia Prague in the five-match championship group with a game to play, but their city rivals cannot now overtake them, despite a 3-2 comeback victory at Sigma Olomouc.
Even if the teams finish level on points, Sparta will win on the tiebreaker as they finished top during the 30-game regular season.
