FOXBORO >> Patriots wide receiver Stefon Diggs kept a smile on his face during his media availability Tuesday through a series of tough questions about a viral boat incident from Memorial Day Weekend on the final day of spring practices, but he wouldn’t break.

Diggs was asked about the video, which saw him pass out a pink substance in a plastic bag to a group of women on a boat.

“Obviously I want to be as candid with you guys as possible,” Diggs said. “I kind of like have a thing where I don’t talk about my personal life with people I don’t know personally. Pretty sure everyone here — men and women — are great people. But kind of keep my personal life personal. I had a conversation with Vrabel, obviously, and I’m going to echo everything that he said. Hope everyone makes good decisions. I had some conversations with people in the building as well. So everything else is everything else and the particulars are all internal.”

Diggs would not reveal what substance was in the bag.

“Obviously it’s a conversation that’s happening internally,” Diggs said. “I can’t have too much of a conversation about it. But I’ve been in this league 10 years. You can format the question many different ways and I’m going to obviously answer it the same way.”

Diggs had a similar response when asked if he knew he was being recorded, if he regretted the incident and what he learned from the experience.

“Obviously I don’t want to be rude and I would hate to repeat myself for the fourth time,” Diggs said. “But again, I’ll repeat myself and say the same thing again. I’m trying to be as polite as possible.”

Diggs, 31, was the Patriots’ highest-profile offensive addition this offseason, signing a three-year, $63.5 million contract in late March. The four-time Pro Bowl selection is returning from a torn ACL, suffered in late October, and has been a limited participant in recent spring practices, including during mandatory minicamp on Monday and Tuesday.

He’s ready to be a full participant in practice whenever the team will allow it, however.

“We’ll see how it goes,” Diggs said when asked if he’ll be ready for the Patriots’ Week 1 matchup against the Raiders on Sept. 7. “Obviously, I don’t make the rules. I’m grinding each and every day, though.

“I can’t do too much of the team stuff, but I’m eager to get out there, so whenever they do press the button, I’m going to be ready. I’m grinding, though, every day.”

Diggs might not be 100%, but he’s flashing speed and change-of-direction ability during the drills in which he’s allowed to participate.

He said his knee is feeling “pretty good.”

“It’s always been a process. I was seven months on Saturday,” Diggs said. “So it’s a nice seven-month reunion, and I feel great. Been out here grinding with the boys. Been definitely a process but it’s on the back end now. I wanted to mix it up a little bit but I don’t make the rules.”

Diggs, who has 10,491 career receiving yards, was asked if he could still be a “number one guy.”

“For who? For myself?” Diggs asked.

For your team.

“100 percent,” Diggs answered.

That’s certainly what the Patriots were hoping when they signed him to his high-priced deal this spring. The guaranteed portions of Diggs’ contract, including his $12 million signing bonus, are dependent on him passing a physical, however.

Diggs was asked if that has occurred yet.

“I haven’t had it yet. We had something like it. Maybe I have passed it, but it’s kind of up to them,” Diggs said. “I’ve just been playing it by ear. … Oh, you’re saying, ‘Have I got the money yet?’ I got to check the account.”

The rest of the Patriots’ wide receiver depth chart is filled out by veterans Mack Hollins and Kendrick Bourne, 2023 draft picks Kayshon Boutte and Demario Douglas, second-year pros Ja’Lynn Polk, Javon Baker and John Jiles, and rookies Kyle Williams, Efton Chism, Demeer Blankumsee and Jeremiah Webb.

Hollins has been a non-participant this spring, and Polk has been limited after an offseason shoulder procedure, leaving Boutte, Douglas and Bourne as the team’s top options.
