Wall won both his fourballs games on his debut in the Vivendi Trophy, but was unable to play any further part in the match and feared it might signal a lengthy lay-off.
Martin Kaymer and Paul Casey, first and second on the European Tour money list, are also missing this week.
Kaymer is recovering from surgery after breaking toes in a go-karting accident, while Casey is still struggling with the torn rib muscle injury that has been bothering him since The Open in July.
In their absence Rory McIlroy, Lee Westwood and Ross Fisher all have a chance to go top of the Race to Dubai standings.
McIlroy and Westwood need a second place finish on Sunday, while Fisher, who last year lost a play-off to Swede Robert Karlsson, would have to take the first prize of just over £485,000.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
