In his final game for the province in Thomond Park, Stander captained Munster to a 31–27 win against Cardiff Blues in round 4 of the Pro14 Rainbow Cup on 28 May 2021. Superficial burns sustained during a fire pit incident caused Stander to be ruled out of Munster's final game of the 2020–21 season, away to Italian side Zebre, bringing to an end Stander's career with Munster.
