SANTA CLARA -- The 49ers had contact with free agent cornerback Eric Wright since Chris Culliver's season-ending injury, coach Jim Harbaugh said Sunday.
Wright remains a possibility to join the 49ers at some point after he is able to pass a physical. The 49ers acquired Wright in a trade from the Tampa Bay Buccaneers on July 19. But the trade voided when he failed a team physical three days later. The Buccaneers promptly released the 28-year-old Wright, making him a free agent.

"We're assessing," Harbaugh said. "There's a process. We won't lay out the plan right now."
When asked if he envisions Wright in the 49ers' future, Harbaugh answered, "I don't have a crystal ball, but there's a process."
Tramaine Brock, who broke training camp in 2011 as the 49ers' third cornerback, was inserted into that role for Sunday's practice behind starters Tarel Brown and Carlos Rogers. Nnamdi Asomugha and Perrish Cox are also in the competition for the job as the No. 3 cornerback.
Culliver, who held that role for the final 13 weeks of 2011 and all of last season, will miss the season with a torn ACL in his left knee.
