Kirk caught three of four targets for 20 yards in Sunday's 26-0 win over the Titans in Week 4.
Kirk was active for a second game after missing the first two weeks of the year with a hamstring injury. He's totaled 12 targets, more than any Houston receiver who has appeared in all four games aside from Nico Collins (31). Kirk will remain the No. 2 wideout for now, but rookie Jayden Higgins, who caught his first NFL touchdown Sunday, could push for the role as the season progresses.
