News: Angerer has decided to retire from football, NFL.com reports.
Impact: Angerer was selected in the second round of the 2010 Draft by the Colts and quickly became a key contributor for Indianapolis. In fact, his career-high 148 tackles (78 solo) in 2011 ranked fourth in the NFL. However, since then, Angerer has endured multiple concussions and underwent microfracture knee surgery last December. To preserve his future health, Angerer has chosen to retire, finishing his four-year career with 327 total tackles.
