A couple of days after signing nine reserve/future free agents, Buffalo signed two more on Wednesday.
The Bills signed S L.J. McCray and LB Xavier Woodson-Luster. Both players spent time on Buffalo's practice squad in 2017.
McCray, 26, was originally signed to the Bills practice squad in October, but was released during Wild Card week to make room for RB Aaron Green when there was a chance the Bills would be without LeSean McCoy heading into their playoff game at Jacksonville.
Woodson-Luster, 22, was signed to Buffalo's practice squad during Christmas week and stayed there through the end of the 2017 campaign.
The Bills now have 12 reserve/future free agents signed in total.
