Pettis (undisclosed) was activated from the active/non-football injury list Wednesday.
Pettis was able to pass a physical and get cleared to compete after being sidelined since the start of training camp. The 27-year-old should be in the mix to earn a depth role in the team's receiving corps; however, with the addition of DJ Moore and Tyler Scott during the offseason, Pettis may find it more difficult to make the Bears' roster this season.
