With no certainty over who will coach them, Scotland's preparations for next week's Quadrangular Series in Ireland have been further undermined by doubts over their fast-bowling contingent.

The Scots face West Indies in Dublin and The Netherlands and Ireland in Belfast, but Dewald Nel has been ruled out of the latter two games by his county, Worcestershire, who have Pro 40 League commitments.

Paul Hoffmann is struggling to arrange time off work so that he can take Nel's place, with Sunday's Irish clash the only game in which he is certain to play.

Worcester coach Steve Rhodes has given Nel his blessing to play in matches where ICC rules demand mandatory release of county players, but the 27-year-old will have to fly back from Dublin on Thursday night to face Essex the next day.

Meanwhile, the Scotland Under 23 squad lost by 116 runs to Ireland after conceding a century to a 16-year-old. Paul Stirling of Cliftonville made an astonishing 110 on a pitch with bite and turn to propel the Irish to a competitive 220 for eight.

Of the Scots' total of 104 in 28.5 overs, 25 runs were extras.
