Jalen Hurd, 24
There’s a real possibility Hurd winds up listed as a tight end this season after missing his rookie year with a back injury. A tight end designation wouldn’t change the versatility Hurd offers the 49ers though. He’s a receiver, who played running back in college for three years before switching positions and schools and having a productive final year as a receiver. He has the size (6-4, 227 pounds) and tenacity to fill out some and play tight end to give the 49ers’ offense an added wrinkle. On the other hand, he fractured his back last season and wasn’t medically cleared to play by the end of the year. General manager John Lynch expects him to be back for the full offseason program, but the injury question looms. He’s arguably the most interesting 49er to watch during the offseason program.
