The Bills released Thomas (knee) from IR with an injury settlement Tuesday, per the league's official transactions log.

Buffalo has placed Thomas (knee) on its injured reserve list, Chris Brown of the Bills' official site reports.

Thomas did not practice Thursday due to a knee injury, Jay Skurski of The Buffalo News reports.
Thomas re-joined the Bills at the tail end of last season after being cut by the team in October. He was already viewed as a longshot to make the final roster, so an injury won't do him any favors.
The Bills released Thomas on Wednesday.
Thomas saw the field for just six defensive snaps in the two games he appeared in thus far in 2018. His release opened the door for the team's claiming of another defensive tackle, Jordan Phillips, off waivers from Miami.
Thomas was called up from the practice squad Saturday, Chris Brown of the Bills' official site reports.
