The fourth division side confirmed the left-back as part of their coaching staff on Monday and will help them in the 2022 season.
The 30-year-old has been without a club since July 2021 when he parted ways with Shakhter Karaganda of Kazahstan.
And it appears, Baah, who shot to fame after winning the maiden edition of football reality show, MTN Soccer Academy, has called quit to pursue coaching.
"It’s with great delight to welcome former RedBull New York and Ghana International player Gideon Baah to the Allentown United coaching staff for 2022!," the club wrote on Twitter.
Baah received a number of prizes for winning football reality show, including cash, car, trip to watch the 2010 FIFA World Cup, and two-week trial at Chelsea FC academy.
Chelsea player and Ghanaian international Michael Essien stated that he was very happy with Baah's performance and urged the club to offer him a contract. Baah later returned to Ghana.
He played for Asante Kotoko before travelling abroad to feature for several clubs including HJK Helsinki and New York Red Bulls.
