HOUSTON -

The Texans wrapped up their preseason 2-2 but the work is beginning for head coach Bill O'Brien to get his roster in place.

As KPRC Local 2 Sports first reported Friday night, O'Brien released former 2nd-round pick, cornerback Brandon Harris. A source says Harris was let go early on Friday.

O'Brien continues to say that the three quarterbacks will be a part of the roster although that could change in the hours and days ahead. 

"Very difficult to bring a guy in and get him ready in one week to be a backup or a number three. It’s a difficult process," said O'Brien. 

"Is it something that we would do if we felt like it was something that would improve the football team, certainly we would look at that. At this point in time, these three guys: Fitzy (Ryan Fitzpatrick) our starter, and Case (Keenum) and Tom (Savage) have worked hard.

"They know the system. Part of it and this is not an excuse, it’s just something I’ve been thinking about all night, but when you play in the preseason, it’s a little bit disjointed in that you play two series here. You play one series here."

You get thrown back into the game here. Part of that, we’re trying to evaluate how you would handle that, but again, it’s very difficult to get into a rhythm. I think we all have to understand that as coaches and understand that these guys have worked very hard and they have improved. Last night was not one of any of our better nights.”

 The Texans have the first shot at any other player on the waiver wire.

“That’s a very difficult process. It’s something that is good for us in the fact that we have the first priority claim on anyone that gets released at this point," said O'Brien Friday afternoon.

"It’s difficult because obviously you have guys here that have worked very hard. It always goes back to doing what’s best for the team. Whatever we think can improve the team, if we think it can improve the team, then we’ll always look to do that. At the same time, it’s what’s best for the team. If what’s best for the team is to make sure that we keep the locker room intact basically as it is right now or as it will be when we get down to 53, then that’s what we should do also," said O'Brien.
