PGA Tour winner JJ Spaun became the second 'JS' to withdraw from this week's AT&T Byron Nelson and TPC Craig Ranch.

Spieth, 29, was forced out of his home event earlier this week as a result of injury.
The three-time major champion is now in a race against time to be fit for next week's US PGA Championship where he goes in search of completing the career grand slam.
No reason was given for Spaun's withdrawal other than he has been replaced in the field by Sweden's Richard S Johnson, who is ranked a lowly 2,248th in the world.
Johnson has won PGA Tour title to his name coming at the 2008 US Bank Championship in Milwaukee.
Spaun is ranked 73rd in the world.
He's had an indifferent start to the PGA Tour season with five missed cuts but two top-10 finishes coming at the Tournament of Champions (T5) and WGC Match Play (T9).
Spaun won his sole PGA Tour title at the 2022 Texas Open at TPC San Antonio.
This week's event is also in Texas.
Spaun was priced up 10th in the betting at 40/1, while Spieth had been as short as 9/1 prior to his WD.
World No.2 Scottie Scheffler starts a warm favourite at 4/1 as he goes in search of his third win on the PGA Tour this year.
Scheffler has also got the captain's armband for our GolfMagic Fantasy team this week.
This week's annual tournament is staged in honour of 52-time PGA Tour winner and 12-time major champion Byron Nelson.
The tournament was established in 1944.
Tom Watson is the record four-time winner having first won in 1975 before adding three in a row from 1978 to 1980.
South Korea's KH Lee is bidding to do the same this week having won the last two renewals in 2021 and 2022.
