He still hasn't made an appearance at Patriots OTAs, but Tom Brady has been working out with Julian Edelman at Gillette Stadium.

Guess who's been a semi-regular showing up to Gillette and working out in the bubble? Tom Brady. Who's he working out with in those throwing sessions? Julian Edelman. Yet still no OTAs — Michael Giardi (@MikeGiardi) June 1, 2018

While Edelman - coming off missing last season after knee surgery - has been participating at Patriots OTAs, Brady has stayed away. Last week, he was in Monaco for promotional events for companies with which he has endorsement deals.

Jeff Howe of The Athletic reports that Brady has made it a point not to be working out in the bubble in the hours his teammates are at OTAs.

While Tom Brady and Julian Edelman have thrown together in the bubble at Gillette this offseason, I’ve been told Brady has not been at the bubble or TB12 during OTAs. Brady didn’t want the optics of being at or near Gillette while teammates were practicing. — Jeff Howe (@jeffphowe) June 1, 2018

Amid reports of tension between coach Bill Belichick and Brady, Patriots owner Robert Kraft said last week that both the quarterback and All-Pro tight end Rob Gronkowski, who has also not participated in the team’s voluntary OTAs, will be at mandatory mini-camp Tuesday through Thursday of next week.

According to Dale Arnold of WEEI, Gronkowski has been working out in the practice bubble as well.

According to @DaleEArnold Gronk is also working out in the Bubble. — Dale & Keefe (@DaleKeefeWEEI) June 1, 2018
