What happened: The absence came one day after Collins hurt his hamstring during practice. Collins had already been limited Wednesday by the same issue in Wire Report's previous update.
Why it matters: The change matters because his practice status moved the wrong way as Houston worked through the week. A second straight injury update makes the next report more consequential than a routine midweek maintenance note.
By the numbers: Practice trend: limited Wednesday, non-participant Thursday, a one-day downgrade on Houston's injury report.
What to watch: Friday's report is the next checkpoint for Collins' availability. Houston's final injury designation will show whether the hamstring issue carries into game day.
