Riyad Mahrez has been cleared to play for Manchester City in the champions' opening Premier League game at West Ham on Saturday after passing a drugs test with the UK Anti-Doping Agency.
Mahrez was left out of City's squad for the Community Shield against Liverpool last Sunday as they awaited medical documentation following surgery he had in Algeria after his country's Africa Cup of Nations triumph.
That paperwork eventually arrived, while the winger had a successful drugs test when UKAD officials made a visit to City's training ground during the week.
"Riyad made a little surgery on his nose after the Africa Cup of Nations," City manager Pep Guardiola told reporters on Friday.
"It is a normal situation, but the doctor, not from the national team, did not send the necessary paperwork. We did not have it in the right moment.
"But after the last week, anti-doping have made the test. Everything is clear and fine. He can play.

"Every time you take something, you have to inform the club and make a list. Everyone knows that.
"We didn't have it in that moment as he did it in Algeria. We had to be careful, so it was better not to use him. It was a precaution." Mahrez's availability is welcome news as Guardiola prepares for a long spell without Leroy Sane.
The German winger suffered an anterior cruciate ligament injury to his right leg against Liverpool and he will be out for at least six months.
His absence means Mahrez will move up the pecking order in City's attack as he begins his second season at the club.
At times last year, the former Leicester player struggled to make an impact, but Guardiola has reviewed his contribution over the close-season.
