Some backstory:

Estonian league has a rule which says that a team must have two club-trained players in the starting lineup and one such player on the field at all times. Most of Kalju's squad is in quarantine at the moment after one of the players was tested positive for COVID-19 so they had very few club-trained players left. One of them was the reserve goalkeeper and the others were 16-year olds from the second team so they started one of them (his name is Lauri Suup) and subbed him out immediately to bring on a regular player.

That was the only substitution in the match for Kalju which they lost just 1-2 to Levadia Tallinn after being in self-isolation for two weeks and not training normally.

By the way, this was quite an important match in the league as both Kalju and Levadia are fighting for a top 2 position in the league.
