What happened: Porter practiced in Dallas after passing his physical and said his back is feeling better as he works day to day. Pittsburgh had added the cornerback to its injury report before ruling him out for Thursday's scheduled game against Cleveland.

Why it matters: The update keeps the Cowboys on track for a possible early look at Porter against Houston after his move from Pittsburgh. It also shifts the immediate focus from the trade to whether Dallas can get him on the field this weekend.

What to watch: His practice status over the next two days will be the clearest indicator ahead of Sunday.
