O'Callaghan handed his

<div>COACH Ian McGeechan insists his British Lions squad have reached the &ldquo;business end&rdquo; of their South African tour as they prepare for the first Test against the world champions on Saturday.<br />&nbsp;</div>
<div>McGeechan has long maintained his final selection for the Durban clash will not be decided until after tonight&rsquo;s tour match with the Southern Kings in Port Elizabeth.<br />&nbsp;</div>
<div>But although the general feeling is that the bulk of those involved tonight will not feature against South Africa, there are several players on view looking to impress for a final time.<br />&nbsp;</div>
<div>One of those is Munster lock Donncha O&rsquo;Callaghan, who takes the captain&rsquo;s armband for the first time. He partners Simon Shaw in the second row, while Scottish duo Euan Murray and Ross Ford and England&rsquo;s Andrew Sheridan complete a powerful tight five unit.&nbsp;<br />&nbsp;</div>
<div>Wales wing Shane Williams has been named in the team but could miss out with a stomach bug. The IRB Player of the Year has not travelled with the squad and Ireland&rsquo;s Tommy Bowe is on stand-by.<br />&nbsp;</div>
<div>McGeechan said: &ldquo;This is Test week and there is a noticeable change in attitude within the touring party. We are now heading towards the business end of the tour and the reason why we have come to South Africa.<br />&nbsp;</div>
<div>&ldquo;As you would expect the immediate focus is the next match against the Southern Kings before attention turns to selection for the First Test for which all players will be considered.&rdquo;<br /><br /> <!--StartFragment--> <strong>LIONS </strong>XV vs SOUTHERN KINGS<br />
