Why the wait on Gronkowski surgery?

The surgical procedure Rob Gronkowski is facing could take up to 12 weeks to recover from, according to reports, yet the Patriots tight end is waiting until mid-June to have the surgery done.

Why isn’t the operation being done immediately in order to ensure Gronkowski doesn’t miss any games? If he had the operation on Monday, for example, Gronkowski could theoretically be ready in mid-August if that 12-week recovery time is accurate.

The reason for the wait, according to a league source, is a precautionary measure to ensure the infection that resulted in Gronkowski undergoing his fourth forearm surgery May 21, is a little further in the rear view mirror.
