After a two-year absence, Louis Rees-Zammit was recalled to a 39-strong Wales squad unveiled Tuesday by new coach Steve Tandy.
The British and Irish Lions winger, who won the last of his 32 caps at the 2023 World Cup, made the switch to American Football in January 2024.

The 24-year-old Bristol player joined the Kansas City Chiefs and then the Jacksonville Jaguars, but did not play a competitive game in the NFL.
His inclusion is a boost for Tandy as he named his squad for November Tests on successive weekends against Argentina, Japan, New Zealand and world champions South Africa.
"It's been really exciting going through the whole process and realising how many good players we've got," said Tandy, who left his role as Scotland defence coach - a position he had held since 2019 - to fill a vacancy created by Warren Gatland's departure in February.
"There's a really good mix of some young guys coming in, mixed with some experience as well. But the overall feeling is really exciting and I can't wait to get the boys into camp on Monday."
Jac Morgan will captain the squad for the campaign, having been on tour with the British and Irish Lions this summer in Australia. Fellow Lion Tomos Williams is also selected for Wales this autumn.
Meanwhile, Edinburgh captain Magnus Bradbury was recalled to the Scotland squad announced Tuesday for next month's Autumn internationals, three years after winning his last cap.
The 30-year-old back-row, who made the last of his 19 Test appearances in 2022, was included in a 45-man squad named by coach Gregor Townsend for November matches at Murrayfield against the United States, New Zealand, Argentina and Tonga.
Captain Sione Tuipulotu was also recalled after missing the Six Nations through injury and then being involved in the British and Irish Lions' series win over Australia.
Uncappped Montpellier back-rower Alexander Masibaka has retained his place after going on the summer tour of the South Pacific.
