Some Patriots-based items on the agenda for this week:

Gronk's fourth surgery. Patriots tight end Rob Gronkowski is scheduled to undergo the fourth surgery on his left forearm on Monday at Massachusetts General Hospital. Doctors feel confident that the infection has been eradicated, but they won't know for sure until they take tests during the procedure and then examine those over the next week.

Patriots organized team activites begin. The next phase of the Patriots' offseason program shifts into a higher gear with players participating in their first organized team acitivities on Monday and Tuesday. The first phase of the offseason program was centered around mostly conditioning, and now the work intensifies with a team-based, on-field focus. "I'm looking forward to getting back out on the field and back to football a little bit; it ramps it up," running back Shane Vereen said last week, in anticipation of the OTAs. Media members will be present for Tuesday's session.

NFL spring meeting in Boston. The NFL is holding its annual spring meeting in Boston on Tuesday. It's a one-day meeting from 8:30 a.m.-5 p.m., and the big item on the agenda is that Super Bowl L and Super Bowl LI will be awarded. The rest of the meeting is essentially reports and discussion on various matters, and with some owners arriving on Monday, there could be some league-wide chatter to monitor from Boston today. Commissioner Roger Goodell will address the media at the end of Tuesday's meeting.
