Penix is expected to be held out of Atlanta's final exhibition game against Jacksonville on Friday, Marc Raimondi of ESPN.com reports.
Penix also didn't play in the Falcons' second preseason contest versus Baltimore on Saturday. Head coach Raheem Morris explained that the team feels it "saw enough last week [in Atlanta's preseason opener] of him and the live stuff," adding that "[Penix] showed us last week enough that we don't have to play him in the preseason." The rookie QB completed nine of 16 passes for 104 yards with no touchdowns or interceptions against Miami in Atlanta's first game of the preseason and is slated to open the regular season as the team's backup behind Kirk Cousins.
