Fourth-year defensive end Yannick Ngakoue will miss the first game of his NFL career when the Jacksonville Jaguars play at Houston on Sunday.Coach Doug Marrone ruled Ngakoue out Friday because of a hamstring injury suffered in the opener.Marrone says: "It's a shame. I spoke to him and he really wants to play. He's like Juli¨¦n Davenport Jersey , 'I want to play. I don't really care. I want to get out there.'" Marrone adds that "you don't really see that a lot, but that's how he's been."Ngakoue is third in franchise history with 29½ sacks.Left tackle Cam Robinson has been cleared to play, but Marrone will hold him out as a precaution. Robinson hyperextended his right knee a few days before the opener. Second-year pro Will Richardson will make his second consecutive start at left tackle.Cornerback A.J. Bouye (hip) and receiver Marqise Lee (knee) are listed as questionable, although Marrone does not expect Bouye to play. Second-year pro Tre Herndon is expected to start in his place.Backup offensive tackle Cedric Ogbuehi (hamstring) and rookie tight end Josh Oliver (hamstring) also are out for the second straight week. When things return to normal, Brennan Scarlett will return to the bench.But that may not be until the start of the regular season J.J. Watt Jersey , so for now he¡¯s a starting outside linebacker for the Texans.Via Aaron Wilson of the , coaches and teammates have been impressed with Scarlett this offseason, while he¡¯s working in the place of Jadeveon Clowney. Clowney could miss training camp, while he waits to sign his one-year, $15.967 million franchise tag deal.¡°Brennan DeAndre Hopkins Jersey , he has improved a whole lot, especially from last year to this year,¡± veteran outside linebacker Whitney Mercilus said. ¡°He¡¯s embraced his role. His pass rush has been on point. His pass coverage has been on point. I¡¯m excited to see exactly what he does this year.¡±Of course, they¡¯ll be more excited to see Clowney return and continue to produce as he has (particularly since he¡¯s making over $939,000 per week) Lamar Miller Jersey , but they think the extended work this offseason is helping Scarlett.The former undrafted rookie from Stanford started three games last year before landing on IR for the third straight year, and had a forced fumble and an interception.¡°Brennan has been with us for a little bit and he has played multiple positions,¡± Texans defensive coordinator Romeo Crennel said. ¡°He can do multiple things. I think he can and will function very well for us.¡±At least until Clowney returns.
