Dons will not be pursuing permanent deals for former Charlton and Palace players
The duo had been on trial with the Dons in the early stages of pre-season, both featuring in the 1-0 loss to Eastbourne Borough in early July.
Parker, who predominately featured as a striker, joined Charlton Athletic in 2019 on a six-month deal. The Antigua & Bermuda international has recorded more than 250 appearances and scored 41 goals during his career.
Pierrick graduated through the Crystal Palace academy to make his first-team debut for the Eagles in a 1-1 draw away to Norwich City in January 2020.
Lambeth-born Pierrick left Palace in 2021 after failing to break into Roy Hodgson’s side consistently to join Danish Superliga outfit Vejle Boldklub.
The 20-year-old winger recently featured for Portsmouth in a pre-season friendly but suffered a knock in a 5-2 win against Leyton Orient.
