Spieth is playing his first event since the Ryder Cup at the Hero World Challenge this week.
He re-injured his wrist after the Ryder Cup while at home making toast for his son.
Originally hurt his wrist in May while playing with his son. Was forced to withdraw from Byron Nelson.
The MRIs didn't show the full extent of his injury. More testing revealed it was his ulnar nerve.
Treating it has involved loosening up his neck, chest and arm rather than resting it.
It's not an inflammation issue. More about managing use and not overusing it.
Has been working with physical therapists over the last couple months.
Says he has to be in tune with his body and listen to when he needs to back off.
Feels he is now pain-free and ready to compete again.
Will continue treatment and therapy even as he returns to golf to prevent future flare ups.
