World number 56 Russell Henley leads by two strokes from seven players after the opening day of the Wyndham Championship with play suspended late on Thursday.

Henley carded an eight-under-62 including an eagle on the fifth hole and three birdies on the final four to open up a two-shot lead at the Sedgefield Country Club in North Carolina.

The American leads from a group of players on six under including Sung Kang, Ted Potter Jr, Michael Thompson, Chris Kirk, Scott Piercy, Hudson Swafford and Adam Hadwin.

A long list of players were a further stroke back at five-under, led by Webb Simpson, Denny McCarthy, Kevin Kisner and Erik van Rooyen.

World number 19 Simpson fought back after a double bogey on the first hole, with eight birdies across his round.

All of the contenders except for Hadwin got through their 18 holes before play was suspended due to darkness after inclement weather had earlier interrupted. Hadwin got through 16 holes for his six under, with the first round to resume on Friday at 7:30am local time.

April's Masters winner Hideki Matsuyama finished his opening round with a one-under-69, double bogeying the fourth hole around birdies on the second and fifth.

Brian Harman, Kevin Na and Will Zalatoris ended the day two under, while American Jason Kokrak improved on his back nine to card an even round following a bogey and double bogey on the 14th and 15th holes.

American Austin Cook, who finished even, was cruelly denied an ace on the 16th when his tee shot horseshoed out of the hole.
