Brown suffered a torn quad in the 2015 season finale and underwent surgery. The left tackle told the Houston Chronicle his rehab is going well and expects to be ready Week 1.
"I'm listening to my body a lot," the nine-year veteran said. "I'm 30 years old and I've played in this league a good amount of time. I'm not going to push it to the point where I have a setback. I'm listening to my body closely, but I feel good and I think I'll be ready to go when the season starts."
Brown's timeline matches up with that of coach Bill O'Brien, who said last month the blindside blocker would sit out OTAs and might miss most of training camp, but should be ready for the regular season.
The recovery period on a repaired quad can range from six to 12 months. Brown believes he's ahead of schedule.
The 303-pound lineman has been able to run on a specialized treadmill that helps support much of his body weight and has been pushing and pulling weighted sleds as part of his rehab.
"That's a big step for me," Brown said of his treadmill work. "I think I'll be running on the field in the next couple of weeks."
