Midfielder Regan Poole has again been called up by Wales Under-21s and is set to miss two Cobblers matches.
The teeenager, who is on loan at Sixfields from Manchester United, has been named in the Wales squad for their UEFA Under 21 Group Eight qualifying matches against Bosnia and Herzegovina and Romania, which take place on Friday November 10, and Tuesday November 14.
The call-up for Wales, who are managed by former Cobblers boss Rob Page, means Poole is unavailable for the Checkatrade Trophy tie with Southampton next Tuesday, and the Sky Bet League One game at Oxford United on November 11.
