Answer based on context:

The Texans became the first team since the Houston Oilers 25 years ago to win a game with negative yards passing, using Demarcus Faggins' 58-yard fumble return for a touchdown, two long returns on special teams and a pair of fumbles by Randal Williams to beat the Oakland Raiders 23-14. David Carr finished 7-of-14 for 32 yards, failing to complete a pass in the final 32 minutes. He was sacked five times for 37 yards, leaving Houston with negative-5 yards passing. The Texans were the first team since the Houston Oilers on Oct. 4, 1981, against Cincinnati to finish with negative yards passing and win. Late in the half, Carr had a run of three straight offensive plays when he was sacked and fumbled the ball. Carr lost the first two fumbles, including one returned 35 yards for a score by Kirk Morrison after Warren Sapp's in the final minute of the half to make it 14-7. Jerome Mathis, who missed the first 11 games recovering from a fractured foot, provided a spark with an 87-yard return of the second-half kickoff. Wali Lundy ran in from the 3 on the next play to tie the game at 14. Mathis was later used as a decoy when Dexter Wynn faked a reverse on a punt return and went 58 yards before being tackled by punter Shane Lechler at the 21. The Texans settled for a 42-yard field goal by Kris Brown to make it 17-14. A pair of fumbles by Williams led to two more field goals by Brown, putting the game out of reach. Rookie DeMeco Ryans led the defense for Houston with 14 solo tackles, a sack, a forced fumble, a fumble recovery and an interception.

How many turnovers did DeMeco Ryans have?
