Williams was everywhere against the Chiefs.
The NFL announced today that Texans defensive end Mario Williams was named AFC Defensive Player of the Week, capturing the award for the first time in his career.
Williams also garnered honors as the Associated Press NFL Player of the Week and Sports Illustrated's Peter King recognized him as the defensive player of the week.
Williams (6-7, 291), keyed the Texans' defense, collecting five tackles—four solos—two sacks, three QB hurries, a fumble recovery, a forced fumble and his first career touchdown in the Texans' Week 1 20-3 win over the Kansas City Chiefs. The win gave the Texans their first three-game winning streak in franchise history.
With the Texans leading 10-0 early in the third quarter, cornerback Jamar Fletcher forced a fumble by Chiefs fullback Kris Wilson that Williams dove on and had the presence of mind to take off for the 38-yard touchdown to give the Texans a 17-0 lead.
Williams, the first pick in the 2006 draft from North Carolina State, recorded a career-high two sacks on the day as the Texans defense limited Chief quarterback Damon Huard to a 53.6 QB rating. The Texans' defense did not allow a touchdown for the eighth straight quarter dating back to last season. Houston's streak stands at 122:41 since they last surrendered a touchdown.
Williams is the ninth Texan to win the Player of the Week award in team history. Williams joins linebacker DeMeco Ryans as members from the 2006 draft class to win the award. Ryans captured the award in Week 13 in 2006. Cornerback Aaron Glenn won the defensive award in Week 14 during the 2002 season.
Williams also is in the running for GMC Defensive Player of the Week honors.
