ENGLEWOOD, Colo. (AP) - The Denver Broncos placed center Tom Nalen on the injured reserve Tuesday.
The 15-year veteran is the last link to the Denver Broncos' Super Bowl titles of the late 1990s. He underwent two surgeries on his left knee this summer and missed the team's first three games.
The Broncos had left him on the roster hoping for his quick return.
Nalen's five Pro Bowls are the most for a Broncos lineman. He's helped Denver to the most rushing yards and the third-fewest sacks in the NFL since 1995.
