HOUSTON -- The Houston Texans didn't make any trades at the trade deadline, but announced some shuffling Tuesday at the bottom of the roster.
Mack's primary role was on special teams, an area where Texans coach Bill O'Brien has said he wants to see improvement.
According to John McClain of the Houston Chronicle and Mark Berman of Houston's Fox 26, the corresponding moves to these included adding linebacker Zac Diles, a 2007 draft pick for the Texans, and running back Ben Malena to the practice squad.
