FOXBOROUGH, Mass. -- One day after the New England Patriots placed Dion Lewis on season-ending injured reserve, sparking questions on the possibility of adding another player at running back, they worked out free agent Daryl Richardson of Abilene Christian.

The 5-foot-10, 196-pound Richardson entered the NFL as a seventh-round draft choice of the St. Louis Rams in 2012. He played in every game as a rookie, totaling 98 carries for 475 yards and 24 receptions for 163 yards as a complement to lead rusher Stephen Jackson.

In 2013, he appeared in eight games (3 starts) and had 69 rushes for 215 yards, as well as 14 receptions for 121 yards.

Richardson was released by the Rams in May of 2014 and claimed by the Jets. He has spent time on the practice squads of the Jets and Texans since, most recently with Houston.

The Patriots have an open spot on their 53-man roster.
