The Texans placed Metchie (knee/illness) on the reserve/non-football illness list Tuesday, Aaron Wilson of ProFootballNetwork.com reports.
This officially rules Metchie out for the first four games of the season, and he's expected to miss the entire year after being diagnosed with Acute Promyelocytic Leukemia earlier this summer. Metchie expects to make a full recovery and return to football at some point.
