Grace was born in Port Talbot and, after playing for Ospreys Under-16s, spent six seasons with St Helens during which he won three Super League Grand Finals and the Challenge Cup, and played six games for Wales in rugby league.
He announced he was switching codes in July 2022 to link up with Racing 92 but ruptured his Achilles while playing for St Helens in August that year.
Grace did not make an appearance for the French Top 14 side after a relapse of the injury in February 2023.
In April, Bath signed Grace on a deal until the end of the 2024-25 season, which includes the option of him staying for the 2025-26 campaign.
Grace had joined Bath in February as he recovered from a long-term injury and played in two friendlies for the club in March against Gloucester and Leinster.
Wales are missing the rested Josh Adams for the summer series with the other back three options in the squad including Liam Williams, Cameron Winnett, Rio Dyer, Jacob Beetham, Josh Hathaway and Mason Grady. The latter will line up at centre against the Springboks this weekend.
