​The Broncos have decided to bring back 27-year-old safety Shamarko Thomas. 

Thomas joined the Broncos this summer after a short stint with the Colts, but did not make Denver's 53-man roster. Cutting and re-signing the player has allowed for Denver to be flexible with his contract.

In his first preseason game with Indianapolis, the safety was ejected for an illegal ​hit. 

This ejection was the first under the NFL's new helmet rule, and yes, it was nasty. Thomas also suffered an eye injury during the preseason. Injuries are nothing new to Shamarko, who has had various holdups in the past.

The safety helps fill out some depth at a position that is unproven. Though Denver has an up-and-coming safety in Justin Simmons and the veteran Darian Stewart, the backups are young and inexperienced, especially with Su'a Cravens' lingering injuries. 

Thomas has never been a true star during his career, but his knowledge and presence should help the whole unit, if only to teach them how not to tackle. 

Denver also waived wide receiver Isaiah McKenzie in order to make room for Thomas.
