Brown's absence could prove a massive blow for Scotland

The Warwickshire star had an injection last week in a bid to be fit for the game, which starts on 16 November.

His place will instead be taken by Heriots bowler Dewald Nel.

Captain Craig Wright said: "It is obviously a blow to lose our most experienced player but we have had very good reports about Dewald's form."

Nel is currently playing his cricket out in Brisbane, Australia.

Scotland secured a place in the last four of the Intercontinental Cup with an eight-wicket win over Ireland in Dublin in August.

They managed that without Brown or Durham's Gavin Hamilton and will be facing a massively inexperienced Kenyan side in Abu Dhabi.

Victory would set up a meeting with either Canada or the United Arab Emirates in the final.
