Joe Morrell has been included in the Wales squad for three international matches.
The Pompey midfielder – who arrived from Luton earlier this month – has been capped 19 times by his country, starting all four of their games at the delayed Euro 2020.
Rob Page's side travel to Helsinki for a friendly contest with Finland on Wednesday, September 1 (7pm kick-off).
They then have two World Cup qualifiers, taking on Belarus in the neutral venue of Russia on Sunday, September 5 (2pm kick-off) before hosting Estonia in Cardiff on Wednesday, September 8 (7.45pm kick-off).
Morrell will miss Pompey's Papa John's Trophy group stage match at AFC Wimbledon while he is away.
