Cape Town - England all-rounder Ben Stokes has a back problem and may miss the third and final test against West Indies in Bridgetown, Barbados starting on Friday.
If Stokes is sidelined England could bring in uncapped Yorkshire batsman Adam Lyth to open with captain Alastair Cook and drop Jonathan Trott down to number three in the order.
The tourists are 1-0 up in the series after winning the second test in Grenada by nine wickets.
