Report: Falcons' Cousins likely to start vs. Dolphins

Atlanta Falcons backup quarterback Kirk Cousins is "highly likely" to start Sunday against the Miami Dolphins, sources told ESPN's Adam Schefter on Saturday.

Michael Penix Jr. suffered a bone bruise in his left knee during last week's 20-10 loss to the San Francisco 49ers. Coach Raheem Morris said Monday that Penix was considered day-to-day. Penix was limited in practice earlier this week and listed Friday as questionable for Sunday's game.

"I'm really confident in our backup," Morris said Friday of Cousins, according to ESPN's Marc Raimondi.

Cousins was the Falcons' starting quarterback until Week 16 last season when the team benched him in favor of Penix, a rookie at the time. The 37-year-old Cousins particularly struggled in the second half of the campaign after injuring his elbow and shoulder, throwing nine interceptions in a five-week stretch. Atlanta finished the season with an 8-9 record, failing to make the playoffs.

Penix, 25, has thrown for 1,408 yards with five touchdowns and three interceptions so far this season. The Falcons hold a 3-3 record and sit third in the NFC South.
