The Rams selected three defensive ends in the 2010 draft and this week traded the first one they selected, fifth-rounder Hall Davis out of Louisiana-Lafayette, to the Redskins.
Davis, who had two sacks against the Cleveland Browns in the Rams second preseason game, was apparently expendable because of fellow rookie tight ends George Selvie and Eugene Sims.
In return, the Rams received 2010 sixth-round pick Dennis Morris, a fullback-tight end from Louisiana Tech. Morris, wearing No. 49, practiced at fullback on Monday with the Rams.
The teams also swapped conditional draft picks.
More roster news from GridironGateway.com's Howard Balzer:
The Rams also waived linebacker Dominic Douglas from injured reserve Monday with an injury settlement.
Offensive lineman Phil Trautwein was waived/injured (knee injury) and will go on injured reserve Tuesday when he clears waivers. If an injury settlement is reached within five days, he could return to the Rams later in the season.
