Houston (CBS Houston) Editor’s Note: Camp Confidential will feature daily news and notes throughout Texans training camp.

The Texans concluded their first day of camp with another practice from 2:30pm until a little before 4:00. Here is what you need to know about practice number 2.

>>> It was a very light session held entirely in the practice bubble. Players wore no pads/helmets and were never moving faster than a jog.

>>> Gary Kubiak said RB Arian Foster – who was placed on the PUP list yesterday due to a strained calf suffered in OTAs – is day to day. He said Foster could be back out there by the end of the week, but isn’t rushing him back.

>>> Nor is Kubiak rushing back safety Ed Reed, who’s also on the PUP list after off-season hip surgery. Kubes said there is no timetable on Reed’s recovery, but said he’s impressed with where Reed is at and expects him to be ready for the season opener.

>>> Reed might not be practicing, but defensive coordinator Wade Phillips has been impressed by the leadership the veteran safety has provided his team: “He is a coach on the field. Right now he is a coach on the sideline. Every meeting, he asks the questions that nobody else would ask because they don’t know the things he knows already and it helps everybody.”

>>> You may not have heard this before…but Phillips thinks J.J. Watt is kind of a big deal. “I said it last year and kind of went overboard with it, but the guy is a really good football player.” When asked where Watt ranked compared to all the players he’d coached (which includes Hall of Famers like Curly Culp, Elvin Bethea, Bruce Smith, and Reggie White) Wade responded: “They were all great players, but they had the will to be better all the time. J.J. has that will, so I think he will have a great career.”

>>> OLB Brooks Reed was held out of the PM session with a sore foot. Offensive tackle Nick Mondek also sat out with a sore foot.

>>> Reed’s colleague Whitney Mercilus knows he has a lot more responsibility this season with Connor Barwin out the door. And especially with two rookie outside linebackers like Sam Montgomery and Trevardo Williams looking to him as a mentor. “It’s weird to think I’m a veteran and trying to teach the rookies…They’ve been coming to me asking for advice.” And they should. Why? Because Mercilus made a fairly successful transition from a 4-3 DE in college to 3-4 OLB as a rookie. Montgomery and Williams will look to do the same thing.

>>> The Texans are gradually getting their players more and more acclimated to practicing outside. After an hour and 20 minutes on the practice field today, they spent the rest of their AM practice – and their entire PM practice – inside the bubble. Kubiak said the team will work outside for an hour and a half at least tomorrow, and will eventually move up to two hours each day.

>>> At today’s AM practice, wide receiver Andre Johnson said he’s the old guy. But Kubiak strongly disagreed. “I don’t think he’s old…I think Dre is getting better. The year he had last year and this off-season has been tremendous.”

>>> Antonio Smith seems to be a bit of a cinefile. When asked if he and J.J. Watt together form a Batman and Robin-esque tandem, Smith said “I’m more like Batman’s teacher…Ra’s Al Ghul. Batman turned on him at the end. That’s more like me, I’m like old sensei. A reporter later asked what he’s seen out of Ed Reed. Smith responded “Now if I’m like the old teacher, Ed Reed is like Yoda. He’s got a lot of wisdom top to bottom.”
