Quenton Nelson will miss 5-12 weeks after undergoing foot surgery, Indianapolis Colts head coach Frank Reich announced Tuesday.
The former Notre Dame guard will have the same surgical procedure on his foot that quarterback Carson Wentz had Monday. Nelson's injury occurred when another player stepped on his foot during training camp practice Monday at Grand Park in Westfield, Indiana.
Nelson has been the most valuable offensive lineman in each of the past two seasons, according to Pro Football Focus' wins above replacement. He received the highest grade among all guards at 90.8 for the 2020 season by PFF.
The Colts picked up Nelson's fifth-year option in April, but he does not have a long-term contract with the team. Indianapolis general manager Chris Ballard has said before he plans to sign Nelson to an extension before he becomes an unrestricted free agent after the 2022 season.
Like Wentz, Nelson could return in time for the Colts' Week 1 game against the Seattle Seahawks on Sept. 12. He could also be out until late October to early November.
Nelson has played in all 48 regular-season games and the Colts' three playoff games since he was selected sixth overall in the 2018 NFL Draft. He has earned AP All-Pro honors in each of his first three seasons -- the first offensive lineman and fifth player since 1970 to receive the honor. The others were Barry Sanders, Keith Jackson, Lawrence Taylor, and Earl Campbell.
