DJ Tim Westwood is set to leave Radio 1 after almost 20 years as part of a shake up of the station's schedule.
The 55-year-old - affectionately known as Big Dawg - currently hosts a two-hour Saturday night show, broadcast on Radio 1 and 1Xtra.
Radio 1 controller Ben Cooper paid tribute to Westwood's 20 years service: "I'd like to thank Tim for the last 20 years on Radio 1. His passion for hip hop is legendary. I wish him all the very best."
The Presenter was injured in a drive-by shooting in south London in 1999 after a gunman opened fire on his stationary Range Rover.
