I guess you'd need to override the outFeature callback, which is
called when the mouse goes out of a feature. You'd possibly need to
modify the overFeature callback as well (to unselect the previously
selected feature).

To override the callbacks do something like that:

var sc = new OpenLayers.Control.SelectFeature(layer, {
    hover: true,
    callbacks: {
        out: function(feature) {
            // your code here
        }, {
        over: function(feature) {
            // your code here
        }
    }
);

Hope this helps,
