Ryan Mallett started last night.
Brian Hoyer started eight days ago.
Who starts next Sunday at New Orleans is still unknown.
Bill O'Brien's Sunday press conference began with questions about the starting quarterback spot, and the
head coach said he's still not put a timeline on when he'll name a starter for the regular season, or the third preseason game.
"When I'm comfortable about making that decision, I'll make it," O'Brien said. "Again, it's all about what's best for the 2015 team."
In the 14-10 loss to the Broncos, Mallett completed 5-of-7 passes for 23 yards.
Hoyer finished with 52 yards by completing 7-of-11 passes.
Neither was able to lead the Texans into the end zone, and neither was picked off. O'Brien repeated what he's said about the competition since OTAs.
"Again, it'll come back to consistency, it'll come back to game management, it'll come back to situational football, who's been the most consistent," O'Brien said. "It's something that we're studying, we're really evaluating, again really at every position, the awareness of what's going on in the game, how they handle different situations."
The Texans will practice on Monday inside the Houston Methodist Training Center, and will play at New Olreans on Sunday afternoon.
