A source reported that Jerome Harrison’s surgery Friday to remove a brain tumor went well and doctors believe that they removed all of the tumor, Chris Mortensen of ESPN is reporting.

Harrison was moved to the reserve / non-football list after the tumor was discovered and his trade to the Philadelphia Eagles was voided.

NFL Players Association medical director Dr. Thom Mayer told ESPN that he wants all players to learn one important lesson from this situation – being truthful with team physicians can have potentially life-saving results.

The pressure in the NFL is so high to play through injuries and be on the field that players can ignore what’s in their best interest. This is an important lesson for everyone, but especially to NFL players.
