Fujita was reinstated by the NFL and cleared to play on Friday, when a three-member appeals panel vacated the suspensions for him, Saints linebacker Jonathan Vilma and defensive end Will Smith, and free-agent defensive lineman Anthony Hargrove.
The Browns are keeping Fujita on an exemption list, allowing them to carry 54 on their roster. Fujita was slowed by a leg injury during the exhibition season and may still not be fully recovered.
With Fujita out and rookie James-Michael Johnson sidelined with an oblique injury, rookie L.J. Fort will start.
The 33-year-old Fujita stretched down on the field before kickoff and briefly chatted with incoming owner Jimmy Haslam III.
