Tom Brady opted against attending the Patriots’ OTAs on Monday, and it’s not yet known whether tight end Rob Gronkowski will follow suit. However, he will be there at some point, Mike Florio of PFT (on Twitter) hears. 
Apparently, there’s a good reason for Gronk potentially skipping Monday and reporting in the near future. Gronk’s reps and the Patriots are discussing a revised contract and, per NFL rules, a reworked deal involving incentives cannot be completed until one year after the last restructuring.
Last year, the Pats and Gronk agreed to tweak the tight end’s deal on May 24th, as James Palmer of NFL.com (on Twitter) notes, so that’s the date to keep an eye on this year. If the two sides can reach an accord in the coming days, Gronk could be on the field starting Thursday.
In 2017, Gronk had incentives added to his deal that gave him the potential to earn some extra cash while protecting the team against another major injury. The 29-year-old hit the top tier of the bonus structure, giving a total salary of $10.75MM by way of his First-Team All-Pro selection.
Gronk bounced back from an injury-riddled year to haul in 69 grabs for 1,084 yards and eight touchdowns. He also had 16 catches for 218 yards and three scores in the postseason.
