What happened: Adam Schefter reported Collins was limited at Wednesday's practice because of a hamstring injury. The designation puts Collins on Houston's Week 2 injury watchlist before the practice week is complete.

Why it matters: Houston has already taken hits to its receiver depth, so any change to Collins' availability carries extra weight as the week moves on. Collins checked in at No. 58 on the NFL Top 100 in July, underscoring how important he is to the Texans offense.

What to watch: Houston's next practice report will show whether Collins remains limited or returns to full work. Any game-status designation later in the week would sharpen the picture for Sunday.
