Odighizuwa (undisclosed) did not participate at the 49ers' training camp practice Wednesday, Nick Wagoner of ESPN.com reports.
Odighizuwa underwent a clean-up procedure to address a lingering elbow injury during the offseason, but it's not clear whether that's related to his current status. Until he's able to practice again, rookie undrafted free agent Bryson Eason could see some practice reps with the first-team defensive line.
