set back

However, this would-be iron man recently suffered a set-back when he was arrested in the central African nation of Chad.

His run to the last 32 in Miami has taken him to 59th in the live rankings before this injury set-back.

This set-back took place while the Zephyr was testing the potential for such aircraft on behalf of the US Army.

It remains to be seen what this set-back means for the mine's operators and their plans for restoration work, which will now be the subject of increased scrutiny.

Murray said he was "not able to serve for essentially 10 days" following that latest set-back and, when asked whether he would appear again at Wimbledon, added it would depend on his physical condition.
