FOXBORO — Javon Baker was an early training camp standout for the Patriots, but the rookie wide receiver has had an inauspicious start to the regular season.

Baker wound up as a healthy scratch in the season-opening win over the Bengals with head coach Jerod Mayo electing instead to dress rookie Ja’Lynn Polk, DeMario Douglas, Tyquan Thornton, K.J. Osborn and Kayshon Boutte.

Mayo was asked Wednesday morning if Baker, a fourth-round pick out of UCF, being listed among the Patriots’ inactives was disciplinary in nature. The young wide receiver went live on Instagram late last month in a profanity-laced video to complain about receiving a ticket from police near Logan Airport, leading Mayo to say it “in no way represents what the organization is about, in no way represents what we are about as a team, or how Javon needs to go out there and represent himself.”

At the time, Mayo said that Baker had been punished but it wouldn’t affect his game status. Baker then went on to tell Pro Football Network’s Dakota Randall that he didn’t regret what he said in the Instagram Live video.

“I don’t want to get into a lot of that,” Mayo said Wednesday when asked if Baker was inactive as punishment. “What I will say is he has to continue to progress and continue to develop, both on the field and off the field, and that’s my responsibility ultimately.”

It’s tough to tell what led Baker to being inactive, because he was buried on the depth chart behind Polk, Douglas, Thornton and Osborn by the end of the summer. Drops and miscommunication plagued Baker from the Patriots’ first preseason game through the end of training camp.

Baker still has plenty of promise if he can put it all together. He averaged an astronomical 21.9 yards per catch on 52 receptions last season at UCF and was once a four-star recruit who began his college career at Alabama.
