Bears quarterback Jay Cutler wore a "very small brace" underneath his orange tennis shoe on his sprained left ankle Wednesday after having the hard cast removed, coach Marc Trestman said.

Cutler on his radio show Monday said he had been fitted that day for a smaller hard cast.

"He’s got the sprain, but there’s stability there, enough stability that they could take it off," Trestman said.

Trestman would not go so far as to say the cast removal increases his optimism about Cutler's availability for the Vikings game on Dec. 1.

"I’m going to stay on a just week-to-week because I’ve stayed pretty consistent with (that)," Trestman said. "I’m really not the doctor. They tell me it’s week-to-week. I try not to put myself in a position where I get overly optimistic about these things. I just take them as they come, so I look at it as being week-to-week right now, and we’ll see where he is on Monday."

Cutler already has been ruled out of Sunday's game against the Rams.
