ALLEN PARK — Safety Louis Delmas (knee) and Chris Houston (ankle) were the only two players not on the field while the media watched practice on Monday morning.

It remains unclear if either one will be ready for Sunday’s season opener against the St. Louis Rams.

Others who had missed time were back including Travis Lewis, Kyle Vanden Bosch, Bill Bentley and Titus Young.

Cornerback Drayton Florence, who was signed on Sunday, was at practice wearing No. 31.

Safety Ricardo Silva was released to make room on the roster for Florence.
