Jerome Harrison's surgery Friday to remove a brain tumor went well and doctors believe they removed all of the tumor, a source told ESPN senior NFL analyst Chris Mortensen.
A condition known as arteriovenous malformation, which is an abnormal connection between veins and arteries that often goes undetected, may have been a contributing factor to the tumor.
Harrison was placed on the reserve/non-football illness list after his trade to the Philadelphia Eagles was voided after the tumor was discovered.
Harrison complained of headaches to Eagles team physician Gary Dorshimer during Wednesday's physical after Philadelphia agreed to trade running back Ronnie Brown to the Lions for Harrison and a draft pick. The doctor ordered an MRI that revealed the tumor.
The test revealed a tumor known as ependymoma in the fourth ventricle of Harrison's brain.
NFL Players Association medial director Dr. Thom Mayer told ESPN that the lesson he wants all players to learn from Harrison's situation is this: Being truthful with team physicians can have a potentially life-saving result.
