Meaning you have a canopy with an open back? Not to be overtly harsh here, but that is a recipe for disaster with wrasses. The tank must be COMPLETELY covered. I even recommend covering the top of a tank inside a canopy, as a canopy typically has a lot of "things" a fish could get caught in or injure themselves on.
If the tank has any avenues of escape for a jumping fish, you need to address that asap.
Never dig up a buried wrasses. They seek refuge in the sand to escape danger (ie - stress) and digging one up simply furthers the perceived danger. It can only negatively impact the chances of success.
The best thing you can do is simply wait. It may be a week or two before you see the fish, assuming it is still in the tank.
