Dolphins coach Tony Sparano said last week that he sees improvement in backup quarterback Pat White. But apparently he doesn’t see enough improvement to put White on the field.

Sparano said today that he doesn’t expect White to take any snaps in Friday’s third preseason game against the Falcons.

White didn’t get on the field in the Dolphins’ second preseason game, either. And in the first game he played just three snaps, long enough to hand off once and kneel down twice at the end of the game.

In the offseason White said he’d rather play baseball than move to receiver, and last month he said he was having personal issues.

White is buried at fourth on the Dolphins’ depth chart behind Chad Henne, Chad Pennington and Tyler Thigpen, and Sparano has said the Dolphins will not keep four quarterbacks. So White, a second-round draft pick in 2009, doesn’t appear to have much of a future in Miami.
