Corbett, selected 33rd overall in the 2018 NFL Draft, is the first major disappointment selected by general manager John Dorsey.
Corbett, who has been inactive on game day 3 times this season, has appeared in 14 games as a reserve.
Corbett failed to win the starting left tackle job as a rookie and this year was beaten out for the starting right guard spot. During training camp Corbett was relegated to third-string and scout team center duties.
After failing to win 2 jobs, there was thought Corbett could replace JC Tretter, who is in the final year of his contract, at center. Tretter will be a free agent next March.
