Lewis was a special teams ace for the Bills last year, totaling 322 special teams snaps across a variety of positions. He also saw some run at both corner and safety, tallying two pass breakups in the process. After gutting their defense for cap purposes last week, bringing back Lewis as a core special teams contributor and a depth option for the secondary was an easy choice for the Bills.

Lewis -- an undrafted rookie out of the University of Buffalo -- battled a concussion through training camp and was cut before Week 1. He'll battle for a depth role in 2020, and he'll likely need to contribute on special teams to secure a spot on the 53-man roster.

Lewis originally suffered the concussion in Buffalo's second preseason game and had to leave the field on a stretcher. The University of Buffalo product has yet to see any action in a regular-season game.

Unfortunately, the rookie from the University of Buffalo suffered an injury in the second preseason game and it didn't look good, as he left on a stretcher. It's going to be difficult for him to make the team at this stage, unless the Bills decide to take one of the injury designation options.
