Mike Singletary just wrapped up his Wednesday press conference. The big piece of news is that running back Frank Gore has what the coach described as "an inside sprain" of his left ankle and likely will be a game-day decision. Gore will not practice today and Singletary said that DeShaun Foster will get the bulk of the practice repetitions this week. If Thomas Clayton is elevated to the active roster, it will be later this week, perhaps Saturday. The good news is that Gore does not have a high-ankle sprain, which almost certainly would have knocked him out a week or more.

Nate Clements, meanwhile, had the pin removed from his thumb and is probable for Sunday's game in Miami. It's unknown whether he will practice today. Others who won't practice are: Walt Harris, Justin Smith and Takeo Spikes, all of whom are being given rest. Eric Heitmann strained his abdomen and will not practice but is expected to play Sunday. Arnaz Battle aggravated his foot sprain and will not practice. Marcus Hudson suffered a concussion Sunday and will not practice.

Allen Rossum (ankle) and Dashon Goldson (knee) are limited. Josh Morgan will go through a full practice ...

Lots of talk about the now-famous "wildcat" formation the Dolphins like to run. The reason it's been effective for Miami, Singletary said, is because the Dolphins have two capable 'backs in Ronnie Brown and Ricky Williams who can get the ball on any given play. The key to stopping it, he said, is not to hesitate and wait to see who gets the ball, but rather to be in the correct position to contain them.

On those wildcat plays, QB Chad Pennington -- who is famously slow afoot -- lines up as a wideout and teams commit a cornerback to cover him. But should they? Pennington said today he hasn't caught a pass since the fifth grade and certainly isn't hoping one comes his way. "I was born to walk; I wasn't born to run," he said. "I don't see any touchdowns coming my way."
