Kadyrov, who sports the hallmark beard of the ultraconservative Muslims known as Salafis, has enforced strict Islamic rules in Chechnya since assuming control in 2004, relying on his security forces to stifle any dissent.
The 25-year-old attacker who has enjoyed a successful season following his move to English Premier League outfit Liverpool, sustained a shoulder injury which saw him forced to leave the field during The Reds' eventual Uefa Champions League final defeat to Real Madrid.
And though he looked to be out of the World Cup with his injury, picked up when he and Sergio Ramos both fell to ground in a grapple-like coming together, the former Chelsea man is thought possibly fit to start the opening game of Egypt's campaign, and even declared himself as "ready" recently.
Salah jogged for about 30 minutes on Monday as his teammates trained on the same pitch in Grozny for the match in Ekaterinburg. "We hope he will be with us for the Uruguay match".
The Egypt global won the PFA player of the year award ahead of Manchester City star Kevin De Bruyne to cap an incredible first season at Liverpool FC.
Doubts persist over Salah's fitness but the Egyptian star said from the team's base in Grozny on Monday that he was "well-prepared" for the tournament.
However Egypt team doctor Mohamed Abou El-Ela placed some caution on any hopes Salah will play a part against Uruguay in their Group A opener this Friday.
