Pruitt agreed to a contract with the 49ers on Wednesday, Tom Pelissero of NFL Network reports.
The 29-year-old tight end will be moving on to his fifth organization since entering the NFL in 2015 as a fifth-round pick. He spent the past season with the Titans, filling a depth role and recording five receptions for 49 yards and a pair of touchdowns. He'll add some more depth to the 49ers' tight end room heading into training camp.
