Izien (groin) was considered to be a full participant at the Lions' walkthrough practice Monday.
Izien was unavailable for the team's 31-30 overtime win against New Orleans on Sunday as a result of a groin issue, but he now appears to be on track to make his season debut in Week 2. The 26-year-old is expected to operate as a top reserve option behind Roger McCreary at slot cornerback, and his first test of the season will come Thursday night against the Bills.
