Dan Campbell promised some lineup changes and he wasn't kidding.

The Miami Dolphins interim coach said Wednesday Bobby McCain is competing to start at cornerback on Sunday against the Baltimore Ravens. The coach said McCain, a rookie, will start opposite Brent Grimes if he has a good week of practice.

That's coachspeak for Bobby McCain is starting.

That means Jamar Taylor who has struggled in recent weeks is out.

Campbell said Brice McCain will be the nickel cornerback.

Yeah, the Taylor infatuation was short. He is on the way to joining a number of other second-round Dolphins picks that did not live up to expectations.

The size of the Miami secondary across the board might become a concern. Brent Grimes and Bobby McCain are 5-10. Brice McCain is 5-9.

But Campbell said he's not worried about that because those three are "gritty" and all will get their hands on receivers at the line of scrimmage to hold them.

On a non-cornerback related issue, Campbell said he expects Mike Pouncey to get some work at practice on Thursday and that suggests his status for Sunday is improving.

Branden Albert, meanwhile, missed practice for rest purposes on Wednesday.
