(Reuters) - Wales have released Hal Robson-Kanu, Rabbi Matondo and Tyler Roberts from the national squad ahead of their World Cup qualifier against the Czech Republic for breaching team protocol, the country's FA said on Monday.
"The three players will be returning to their respective clubs this afternoon," FAW said in a statement. "The FAW will not be making any further comment."
While no details of the breach were given, Leeds United's Roberts took to Instagram to apologise for breaking curfew.
"Gutted to be leaving the camp early, but rules are rules and I shouldn't have been up in the hotel later than the set time," he wrote.
"Sorry to the team, staff and Wales fans. I will continue to work as hard as I can to earn my place in the squad for the Euros."
Wales lost 3-1 in their first qualifier against Belgium last week but beat Mexico in a friendly over the weekend. They play group leaders Czech Republic in Cardiff on Tuesday.
