Viktor Hovland, the No. 4 player in the World Golf Ranking, and No. 5 Xander Schauffele have both withdrawn from this week’s WM Phoenix Open, the PGA Tour announced Monday.

Hovland finished in a tie for 58th at the AT&T Pebble Beach Pro-Am, beating only 14 players in the limited field event. He opened with a 69 last Thursday, but then struggled to consecutive 72s before the tournament was shortened to 54 holes due to weather.

It was Hovland’s first start since finished tied for 22nd at The Sentry, which also featured a limited field.

Victor Perez will replace Hovland in the field at the Phoenix Open. Davis Riley has also withdrawn and has been replaced by Ryan Fox, while Alexander Björk replaces Schauffele.
