The Texans and Bills are playing what could end up being one of the best games of the regular season.
The back-and-forth has led to five lead changes.
The Bills lead 24-21 at halftime, gaining 224 yards against one of the NFLâÂÂs best defenses.
Josh Allen, who is 0-4 in Houston in his career, is 8-of-11 for 163 yards and a touchdown, a 43-yarder to DJ Moore. He has run for touchdowns of 21 yards and 1 yard and has 24 yards on four carries.
Moore, an offseason acquisition, has three catches for 76 yards and has drawn a 46-yard pass interference penalty on Kamari Lassiter in the end zone that set up AllenâÂÂs 1-yard score.
James Cook has six carries for 37 yards.
The Bills have not punted, but Allen was stopped for a 2-yard loss on fourth-and-1 at the Houston 34 on the Billsâ first drive. Buffalo had to settle for a field goal after it had 12 players in the huddle on fourth-and-1 from the Houston 23 on its second drive.
The Texans have 215 yards, having punted once and have one turnover, which was a C.J. Stroud fumble on a strip-sack by Greg Rousseau that Ed Oliver recovered.
Stroud is 12-of-16 for 123 yards and a touchdown, a 12-yard pass to Nico Collins with 26 seconds left in the half. Collins has three catches for 46 yards. David Montgomery has 13 carries for 52 yards and two touchdowns.
