What happened: Patriots head coach Mike Vrabel confirmed that second-round pick Gabe Jacas recently underwent a "clean-up" knee procedure. Jacas remains the NFL's only unsigned second-round selection as the team reportedly seeks specific contract language regarding his recent medical history.

Why it matters: The standoff involves pre-draft flags for a shoulder labral tear and a foot stress fracture, which have prevented the same Gabe Jacas who was recently sidelined from reaching a standard participation agreement. New England traded up to select the Illinois edge rusher, whose 27 collegiate sacks are expected to bolster a defense seeking more consistent pressure.

What to watch: The Patriots expect Jacas to be physically ready for the start of training camp on July 25, though his contract must be finalized first.
