As we previously reported in October, Pro Bowl left tackle Chris Samuels plans to retire because of a severe neck injury, and he is expected to announce his decision in a news conference Thursday at Redskins Park.

Samuels consulted with many specialists, several of whom warned him about the possibility of becoming paralyzed if he attempted to prolong his career, people familiar with the situation said, but questions about his playing status lingered publicly because Samuels declined to officially announce he would not return for an 11th season with the Redskins.
