Dorsett played just four snaps and failed to catch his lone target in Sunday's 20-20 tie with Indianapolis.
After a promising three-game stint with the Texans last December, Dorsett put together a good preseason that suggested a bigger role awaited him than a four-snap cameo. Chris Moore (34 snaps) and Chris Conley (10 snaps), who was elevated from the practice squad, got more run that Dorsett in Houston's opener.
