Attorney Daniel S. Chamberlain said he estimates that Phillips could collect $1.4 million from the settlement between the league and retired players.

Chamberlain, who said he believes brain trauma Phillips suffered while playing football may have contributed to his longtime legal problems, told USA Today that he is helping Phillips retain a criminal defense attorney in the murder case.

A first-round pick in the 1996 NFL Draft by the St. Louis Rams, Phillips played three seasons in the league. Chamberlain said he used an equation based on the number of games and seasons Phillips played in estimating that he would be entitled to the $1.4 million for brain trauma suffered during his NFL career.

Phillips, 40, is serving a 31-year sentence at Kern Valley State Prison in California for assaulting a former girlfriend and driving his car into three teenagers.

Phillips, who has entered a not-guilty plea in the death of then-cellmate Damion Soward, claims he acted in self-defense, according to the Kern County public defender’s office.
