Thomas has been suspended by the NFL for the first three games of the NFL regular season, Aaron Wilson of KPRC 2 Houston reports.
The 49ers waived Thomas from IR with an injury settlement in late August. The linebacker appears to have gotten over an undisclosed issue, but he has now been given a suspension for an undisclosed reason. Thomas remains a free agent and will be able to help any team he signs with once his three-game suspension has passed.
