Brady recently had 12 stitches removed from his throwing hand and admitted on Tuesday that the injury is far from fully healed.
"It's getting better. It's not quite where I want to be, so I'm just trying to protect it the best way I can," the 40-year-old Brady said. "It's obviously a very important part of my body for a quarterback, so I want it to be as healthy as possible for the game on Sunday."
The Patriots will face the Philadelphia Eagles in Super Bowl LII on Sunday (6:30 p.m. ET).
Brady sported a black glove that he said was made exclusively for him by Under Armour.
"Under Armour just made it for me," Brady said. "It's a great glove. It's got a lot of recovery in it, and that's what I need at this time."
Brady initially sustained the injury after colliding with running back Rex Burkhead on a handoff attempt during practice.
Brady played with tape covering the wound on Jan. 21, completing 26 of 38 passes for 290 yards and two touchdowns in New England's 24-20 win over the Jacksonville Jaguars in the AFC Championship Game.
