Irving, TX (SportsNetwork.com) - The Dallas Cowboys released defensive tackle Amobi Okoye on Wednesday.

Okoye had one season remaining on his two-year contract but never played a down for Dallas.

The 27-year-old was on reserve/non-football injury list in 2014 and has not appeared in a game since 2012 with Chicago.

In 2013, Okoye was diagnosed with anti-NMDA receptor encephalitis, an extremely rare condition that caused him to suffer from seizures. He had to be placed in a medically induced coma and undergo physical therapy to restore some brain functions.

Okoye was drafted 10th overall in the 2007 draft at 19 years old, making him the youngest first-round selection in NFL history. He has accumulated 16 sacks in 87 career games (59 starts) with the Texans and Chicago Bears.
