Texans star receiver Nico Collins is 'week to week' with hamstring injury

The Houston Texans improved to 4-1 with a thrilling victory over Buffalo on Sunday for their best start since opening the 2012 season with five straight wins. But the win came with a cost as Nico Collins, who leads the NFL with 567 yards receiving, injured his hamstring and will likely be out this week. 

Collins left the 23-20 victory Sunday after scoring on a 67-yard reception late in the first quarter.

Coach DeMeco Ryans didn't answer directly when asked if he would play on Sunday, but his answer made it sound as if Houston could be without him for a while.

"He's in good spirits (but) of course, with the hamstring, it takes a couple of weeks for a hamstring," Ryans said Monday. "So we'll evaluate that on a week-to-week basis to see when we can get him back."

If he's unable to play Sunday, it will put even more stress on an offense that is already without running back Joe Mixon. He had 159 yards rushing in the team's opener but was injured in Week 2 and hasn't played since. Ryans said he's improving but was unsure when he'd be back.

The Texans built a 20-3 lead against the Bills but struggled offensively for most of the second half with Collins out.

Quarterback C.J. Stroud threw an interception and had his first fumble this season on a sack in the fourth quarter to allow the Bills to tie it, before Ka'imi Fairbairn's 59-yard field goal won it on the final play.

"The first half went really well. We were moving the ball like we wanted, running the ball," Stroud said. "In the second half … we were just shooting ourselves in the foot again, just taking penalties. I missed a couple of reads on my throws and had the two turnovers. When you play like that, you give them opportunities to come back."
