The 30-year-old - who linked up with his national team this week for the March international break - initially gave a positive result and was self-isolating in line with current regulations. Klich was due to travel to Budapest on yesterday ahead of a clash with Hungary on this evening in Poland’s opening World Cup qualifier ahead of Qatar 2022.
It was announced by the Polish FA that he would miss his nation’s first game in Group I after returning a positive result for coronavirus.
In a statement made by media officer Jakub Kwiatkowski, it was said that Klich would self-isolate before undergoing another test to confirm the result. The Whites midfielder, though, has now tested negative for the virus after a further examination was administered.
It remains to be seen whether Klich will link up with his international team-mates in Hungary after being given the all clear. Reports in Poland have suggested he will have to produce another negative test before any decision is made over his involvement for the rest of the international break.
This would mean Klich will miss the game against Hungary but potentially be available against Andorra (March 28) and England (March 31) in the coming days.
Poland are facing a busy triple-header of matches as they prepare for three World Cup qualifiers in the space of 10 days.
He has made fleeting appearances from the bench in recent weeks owing to a drop in form, and has admitted he has felt a little tired of late.
“I admit that yes, that’s why I’ve been resting more in the club lately,” he told the Polish media this week. “I started two matches on the bench.
“Over the last three years I have ‘loaded’ some of these [international] meetings, and I have not had any holidays.
“Fortunately, I was avoiding more serious injuries, but minor ones started to happen to me. From overload, from intensity. My joints don’t hurt yet, I’m only 30 years old, but something hurt.”
He added: “At the club, we also train very hard between meetings, so it’s hard to regain freshness. I hope to catch my breath, because I have the best matches when I am physically prepared.”
