Gibson agreed to a 10-day contract with the Pistons on Wednesday, Adrian Wojnarowski of ESPN reports.
The Pistons are healthy in the frontcourt at the moment, so Gibson may not be a regular part of head coach Monty Williams' rotation and may be joining Detroit primarily to serve in a mentorship role for the team's young big men. Gibson has previously made 16 appearances for the Knicks this season, averaging 1.0 points and 1.8 rebounds in 10.3 minutes per contest.
