What happened: New England listed Ben Brown with a knee issue and TreVeyon Henderson with an ankle issue Sunday. Christian Barmore had been managed at times during training camp.
Why it matters: The absences leave three position groups facing Week 1 availability questions across the defensive line, offensive line and backfield. Brown's knee issue dates to the preseason opener.
By the numbers: The Patriots listed three nonparticipants: two with knee issues and one with an ankle issue.
What to watch: The next practice report will show whether any of the three return before the opener.
