Coach Andy Reid said on Wednesday that Westbrook did "perfect" on his testing and is "ready to roll" for the NFC East-leading Eagles (10-4) in Sunday's home game.
The former All-Pro running back has missed the last five games after suffering his second concussion in three weeks against San Diego on Nov. 15. His first career concussion came against Washington on Oct. 26. Westbrook sat out two games before returning prematurely against the Chargers.
Westbrook will likely have a limited role in the offense, sharing plays with halfback LeSean McCoy and fullback Leonard Weaver.
