Houston cut Phillips on Monday, Aaron Wilson of KPRC 2 Houston reports.
Phillips totaled 88 tackles, including 3.0 sacks, over 20 regular-season games during his first three seasons in the league with the Browns. However, he missed all of last year due to a torn pectoral muscle and was then signed to a one-year deal by the Texans in April. Phillips won't make the 53-man roster, however, and will now likely seek work with another organization.
