Broad, who flew home early from the Test series in India due to a heel injury last December, is yet to recover fully. And Miller feels that the selectors will have to make sure that he is used in the best possible way for English cricket.
"The concern is that there have been two or three niggles that have affected his form and availability," Miller told reporters here.
"Anybody with an injury is a concern to us and we've got to manage workloads as best as we can, that's why we're continually looking at other players. We will look at it and make sure he's used in the best possible way for English cricket. He knows that," he added.
