Could someone please provide info on T. Lewis and T. Burgess?

It's hard to keep up with the rookies, Terrell Lewis and Terrell Burgess, who both looked good last night. Is Lewis now healthy enough to be a contributor for the rest of the season? What were the injuries that held him back? Does it appear that he could help to solidify the defense? Any updates on the injury that knocked Burgess out of the game?
