The health status of Tampa Bay cornerback Darrelle Revis is very much up in the air for Sunday’s game with Carolina.

Revis suffered a groin injury against Detroit. Revis, who did not practice Wednesday, declined to discuss the injury with the media. Coach Greg Schiano wouldn’t divulge details about an MRI that was performed on Revis on Monday.

“He’ll be day to day, so that should tell you it’s not real bad,’’ Schiano said. “Will he play Sunday? I don’t know. We’ve got to figure that out.’’

After Revis was injured against Detroit, rookie Johnthan Banks spent most of the rest of the game covering Calvin Johnson and did an adequate job. Schiano said the Bucs considered several options before deciding to put Banks on Johnson.

“It wasn’t an easy decision,’’ Schiano said. “As a matter of fact, we took the field thinking that we might just play right and left and whoever got him got him. Then, we got on the field and it was just a gut feeling, let’s get Johnthan on him. Johnthan, you’ve got to remember was coming off an injury [shoulder]. Johnthan had gotten banged, so it wasn’t like he had a full week of practice, either. Sometimes you get a feeling.’’

But Schiano’s not ready to say if Banks will defend Steve Smith if Revis isn’t ready to play against Carolina. Schiano said Revis’ situation complicates how the Bucs will game plan for the Panthers.
