AJ McCarron and wife Katherine Webb are expecting a baby boy, and at the end of last week, Webb shared the latest baby bump photo of her son.

Katherine Webb Responds To Weight Criticism

As McCarron prepares to take on the Denver Broncos on Monday Night Football, his model wife shared the new picture with her fans and followers on Instagram.

"Bubs trying to make an appearance today for the Doc," Webb captioned the photo. "Some days he pokes out more than others but he's in there lol #almost5months."

Later tonight, McCarron will take on Andy Dalton's role as quarterback for the Cincinnati Bengals after their previous starter, Andy Dalton, injured his thumb while attempting to make a tackle during a previous game, and his wife, for one, is completely confident in his ability to take on the starting position.

"He could take us to the Super Bowl," Webb told ESPN, via Cincy Jungle. "I thought about that [Sunday] for the first time and it just kind of gave me chills. And at the same time, I have Andy in the back of my mind. Andy has taken us through the whole season and in my mind, I'm like, 'I would love for AJ just to be able to do it for him and for the team.'"

"He's definitely a perfectionist when it comes to his craft," she continued. "So he wants everything to be on point, and he knows exactly what he has to do and whenever he makes a mistake, it's horrible. He takes it so bad. That's just the way he is."
