Taking to Twitter, South Korean reporter Sungmo Lee has shared what he knows in an injury update on Tottenham Hotspur superstar Son Heung-min.

The Lowdown: Son suffers knock...

After a torrid international break for Spurs, it is now time to return to Hotspur Way for damage control as both supporters and manager Nuno Espirito Santo pray for the best.

Among the players to be shrouded by fitness concerns is superstar forward Son, who picked up niggling calf concerns in training for his country on Monday (Korean Football Association via Sky Sports).

Oliver Skipp, Ryan Sessegnon and Steven Bergwijn are other players who Spurs could be without for the Crystal Palace clash this Saturday depending on developments, while Giovani Lo Celso, Cristian Romero and Davinson Sanchez are training in Croatia following their South American fiascos (Dan Kilpatrick).

Lee has now shared an update on Son, and there could be a hint of good news for Tottenham.

The Latest: Lee shares Son update...

Taking to Twitter, the journalist has shared a three-word message from one of his sources despite there being no official update from the KFA on Son's injury.

Indeed, in what could be a boost for Nuno and Tottenham, Lee has heard 'it's not serious', but whether the 29-year-old can play against Crystal Palace this weekend is still a doubt.

The reporter added that Son looked 'OK' at the airport for his flight back to north London.

The Verdict: Fingers crossed...

Son's injury not being a serious one would certainly come as a massive boost for Spurs and Nuno in particular.

The Portuguese head coach has started life brilliantly at Tottenham, enjoying a 100% winning run over his first three Premier League matches.

Nuno will want to continue that momentum and it's safe to say that Spurs' 2020/21 PFA Premier League Team of the Year member will be a huge part of it.
