Seized spark plug Northstar engine

Good Morning to All,

I have an 2005 Cadillac Deville with a V8 4.6 L Northstar engine that has around 85,000 miles on it. The mechanic is pulling code of a misfire at the 3rd cylinder, but is reporting he cannot remove the spark plug to make the repair,as it is seized. I am reaching out to see if anyone has come across this situation and could give us some direction....it would be greatly appreciated.

Thank You,
Ginger
