Bristol Rovers have signed Rotherham United defender Trevor Clarke and Wales Under-21 midfielder Sion Spence on a season-long loan from Crystal Palace.
Spence, 20, has yet to feature for the Palace first team, having moved to the club in September last year after beginning his career at Cardiff City.
He scored seven goals in 15 games for Palace's under-23 side last season.
Clarke, who moved to the Millers from Shamrock Rovers in 2019, has been capped at under-21 level by the Republic of Ireland and played in the Europa League.
He played nine times in the Championship for Rotherham last season.
