However, San Francisco have since lost fellow cornerback Chris Culliver to a season-ending knee injury and are looking at Wright to replace the 24-year-old.
Asked whether there had been contact between the 49ers and Wright, coach Jim Harbaugh told reporters: "I believe so. We're assessing. I don't have a crystal ball, but there's a process."
Wright had only spent one season at the Buccaneers despite signing a five-year contract with the franchise.
