The Facts:
According to ESPN's Chris Mortensen, Darnold still has hurdles to clear to play in Week 5. Darnold says he will have more tests Monday on his spleen. If it's not as enlarged, he can begin practicing and working out.
Diehards Line:
Mortensen added that Darnold's cardio has been limited to walking and riding a stationary bike. He's not a lock to return this week, but hopeful after missing two games with mononucleosis.
