A source at Baylor said Hurd will switch positions to wide receiver.
In his Tennessee career, Hurd rushed for 2,638 yards and 26 total touchdowns before leaving the Volunteers in the middle of an injury-plagued 2016 season.
The junior reportedly also visited Ohio State and Louisville before choosing Baylor.
Because he's not a graduate transfer, Hurd won't be eligible until the 2018 season.
The Bears played their annual spring game Saturday shortly before Hurd revealed his decision.
