According to multiple reports, Brady is nursing a left shoulder injury he first sustained in New England's Week 4 loss to Carolina on October 1 and re-aggravated in last Thursday's win in Tampa Bay. To this point, Brady has already been sacked one more time in five games than he was all of past year.
The Patriots don't have to submit an injury report until Wednesday.
Cornerback Eric Rowe was also not spotted at the beginning of practice. "I'll be there next Sunday".
Asked in the postgame press conference about the hits he took Thursday night, Brady said, "Just football".
Otherwise, Brady's only other extended absence has come in the form of a four-game suspension at the start of last season for his role in the Deflategate scandal. So it's a good day for the Patriots to rest Brady without having to disclose a reason for him not being on the field. The team doesn't have another quarterback on its roster or practice squad after releasing Taylor Heinicke from the practice squad Monday.
"I think that's part of the conditioning that you do in the offseason, to prepare yourself for taking hits", he said (via ESPN). He also took some blame for it, saying he isn't getting rid of the ball quickly enough.
Specifically, Brady wants to see himself play better in the red zone, where the Patriots have 12 touchdowns in 22 trips.
