The Texans begin preseason Monday night at Reliant Stadium against the New York Jets. Andre Johnson (finger) and Jacoby Jones (ankle) might not play. Three running backs - Arian Foster, Ben Tate and Steve Slaton - have hamstring injuries. Darling, 29, ran a 4.4 40-yard dash for the Texans after the Thursday morning practice. He passed a physical. Darling (6-1, 213) hasn't played in the NFL since the 2009 preseason when he suffered a torn anterior cruciate knee ligament. In 2010, he played for Omaha of the United Football League. Darling grew up in Houston and starred with his twin brother, Devaughn, at Stephen F. Austin High School. The Darlings went to Florida State. Devaughn died in 2001 while the brothers were working out at Florida State. Devard transferred to Washington State and was drafted in the third round by Baltimore in 2004. He played four seasons with the Ravens and one with the Chiefs before suffering the injury. Williams grew up in Richmond and played at Foster High School. He went to Tennessee State. He was with Kansas City in 2009 and was on Seattle's practice squad in 2010.
