Allen (heel) didn't take part in Thursday's practice.
Allen was able to suit up Week 1 against the Titans after going limited, limited and full on the first three practice reports of the season due to a heel injury. He's kicked off this week with back-to-back absences, but coach Matt Eberflus said Wednesday that the veteran wide receiver was getting the day off for rest purposes, per Courtney Cronin of ESPN.com. Position mate Rome Odunze (knee) also hasn't practiced this week, so Friday's report may be telling for the duo's odds to suit up Sunday in Houston.
