The Dolphins released White on Sunday, Adam Schefter of ESPN reports.
White had been competing with Skylar Thompson for the No. 2 quarterback role throughout camp, and the move signals that Thompson has emerged on top in that job battle. The 29-year-old White completed just 20 of 43 pass attempts for 179 yards without a touchdown or interception during the preseason, but he's had enough in-game NFL experience with some success -- specifically in 2021 and 2022 with the Jets -- to be an appealing option for teams needing quarterback depth.
