As long as they plan new events to promote the single it will be able to chart. Especially when the events are on monday or if they only submit the weekend sales on monday. As it's counted on monday it will also mean another week in the chart.
With this salesnumber it's possible that the 5th week will have higher sales then the soon to be announced 4th week sales. It will be interesting to see how close the total can come to 50,000.
