In August 2020, Plogmann extended his contract with Werder Bremen and joined 3. Liga side SV Meppen, managed by former Werder Bremen player Torsten Frings, on a season-long loan.[6] He started the season as Meppen's first-choice goalkeeper, but suffered a severe knee injury on his 8th appearance for the club in a match against Dynamo Dresden on 31 October 2020 and was ruled out for several months after undergoing surgery.[7][8] As a result, the loan was cut short in February 2021 and Plogmann returned to Werder Bremen to continue his rehabilitation.[8]
