Porter will make his Cowboys debut against the Texans on Sunday but will have his snaps limited, Jeremy Fowler of ESPN.com reports.
The expectation is that Porter sees about 30 defensive snaps during Sunday's road contest. The fourth-year pro was acquired by the Cowboys from the Steelers on Wednesday and should start opposite DaRon Bland at outside cornerback, with rookie first-rounder Caleb Downs and safeties Markquese Bell and Malik Hooker rounding out the starting secondary for Dallas.
