At this point, there's nothing wrong with sitting tight and waiting for Edgar to return. However, there's also nothing wrong with asking around if there's any interest in him, perhaps from a team in need of a boost in average. You're in a good position: you don't have to make a deal, but can jump on an offer that you like. Don't deal him for peanuts, but if you can get a decent upgrade somewhere (2b, perhaps?), I wouldn't hesitate to trade him.
