Following a two-hour weather delay, Henley got off to a solid start, parring his first three holes before a bogey at the par-4 13th, his fourth hole of the day.
Henley recovered with back-to-back birdies at Nos. 14 and 15, but again slipped with a bogey at 16 and a double bogey at 17. He then birdied 18 to close out a wild, front-nine 1-over 37.
After making the turn, Henley bogeyed the first hole to fall to 2 over. He then parred his next two holes to remain on that number as play was again suspended, this time for the day, at 7:55 p.m. ET due to the threat of inclement weather.
One of Henley's playing competitors, Stephen Gangluff, held the overnight lead, playing his first 12 holes in 8 under.
They were in the last threesome out on Thursday.
The first round resumed at 7:50 a.m ET Friday and Henley played his final six holes at 1-under par with five pars and a birdie at the long par-5 6th hole. He finished his first round at 1-over par and will need to go low in Rd. 2 to make the cut and play the weekend.
This is Henley's second Nationwide Tour exemption of the season. He missed the cut by two strokes at the Henrico County Open in Richmond, Va.
He qualified for last week's FedEx St. Jude Classic on the PGA Tour, but shot 79-80 to also miss the cut.
Henley, who outlasted nine other competitors in the second installment of The Golf Channels popular reality series, has four more Nationwide Tour exemptions to use: next week's LaSalle Bank Open (Chicago, Ill.), the Knoxville Open (Knoxville, Tenn.), the Lake Erie Charity Classic (Erie, Pa.) and the National Mining Association Pete Dye Classic (Bridgeport, W. Va.).
