However, the duo have a chance to retain their playing status on the major tour through the second-tier Web.com Tour Finals.
The Finals consist of a four-tournament series which gives out PGA Tour cards to the top 25 earners over the four tournaments, and Alker and Wilkinson are right in the mix.
The PGA Tour hopefuls are currently in the third tournament of the four, having played two rounds at the Nationwide Children's Hospital Championship, where Alker (tied 11th) and Wilkinson (tied 14th) are both playing strongly.
The strong performances sees Alker sits in 23rd and Wilkinson in 27th on the Finals leaderboard - right on the border of the top 25 which will see their cards stamped for PGA Tour inclusion next season.
If the duo can put together a strong performance over the weekend coupled with a solid final showing at the Web.com Tour Championship finale next weekend, Lee could find himself in familiar company for a second straight season on the PGA Tour.
