Dustin Johnson has officially withdrawn from the AT&T Byron Nelson with a knee injury. Greg Chalmers will replace him. Brandon Hagy and Robert Streb were also two other WDs that took place recently.

Greg Chalmers
NOTE: Sangmoon Bae, who was first alternate, passed on the spot in favor of the @visitknoxopen. https://t.co/1f9Cn8fYlr
Johnson was listed at +900 on FanDuel Sportsbook, so his withdrawal will shake up the top end of the odds board quite a bit.
