The Jets suffered a few concussions last night and here is the injury update that Todd Bowles provided after the game.

Here’s a listing on the studs and duds from Week 2 of the Jets’ preseason. New York will look to get back on track this Friday when it hosts the 1-0 Atlanta Falcons at MetLife Stadium.

Richardson will serve a four-game suspension for violating the NFL’s substance abuse policy. This could develop into a battle between two first-round picks assuming Muhammad Wilkerson finally gets an extension.

New York Jets wide receiver DeVier Posey (89) catches a pass for a touchdown as Atlanta Falcons’ … Quarterback Matt Ryan completed 4 of 5 passes for 75 yards and a touchdown, with a flawless quarterback rating.

Petty didn’t take the safe route. He finished 9 of 15 for 78 yards, most of that coming on three completions to Jimmy Graham. But if Petty is thrust into a starting position in 2015, the Jets’ season is likely over. Matt Ryan and the Falcons’ starters had a quick and efficient night, scoring two touchdowns less than 10 minutes in. Jaiquawn Jarrett started in his place.

The reserves were unable to hold that lead however, and were eventually bested 30-22. Petty showed dramatic improvement after an absolutely miserable showing in week 1.

In the fallout of Robert Griffin III’s latest injury, Jets insider Manish Mehta explores the butterfly effect of how an alternate outcome in the team’s head coaching search this offseason would have directly affected the Redskins. He typically lined up at defensive end in college and had nearly no coverage responsibilities. Petty also showed poor pocket awareness, getting stripped for a fumble in the red zone. Antone Smith is also out as Terron Ward could get another start. We have a bunch of smart guys on the offensive side that will be able to learn from [this] and get better. And if they don’t, they can expect more gassers in practice on Monday morning.

For the second straight game, the Jets’ starting defense allowed the other team’s offense to move quickly down the field for a touchdown on its first possession. Welker totaled 778 yards and 10 touchdowns that season. Evans had one reception for 7 yards. He rarely went though any progressions and had his mind already made up about where he was going with the ball as the Jets offense broke the huddle.

Decker and Fitzpatrick have two preseason games to get on the same page.

Kerley, who finds himself in a competition for playing time with 2014 draft pick Quincy Enunwa, tweeted a message to Jets fans Saturday morning. All-Pro safety Earl Thomas will not.
