"The Texans have hired Karl Dorrell as their new quarterbacks coach to replace Greg Knapp.
Knapp, who did an outstanding job preparing rookie T.J. Yates last season, was hired last week as the new offensive coordinator for the Oakland Raiders.
Dorrell, 48, has known Texans coach Gary Kubiak since 1995. That was Kubiak's first season as the offensive coordinator for the Denver Broncos. Dorrell was the offensive coordinator at the University of Colorado."
