Ivory has an extensive injury history over his NFL career, largely due to his battering ram style of play. When the Jets traded for him, Jets GM John Idzik said Ivory is "a very physical, violent runner."
As a rookie in 2010, Ivory suffered a season-ending foot injury in the last game of the year after battling injuries all season.
During the start of the 2011 season, Ivory spent the first six games on the Physically Unable to Perform list and only played six games before only playing six again during the 2012 season.
Last summer in his first year with the Jets, Ivory was limited throughout much of training camp, leading to a slow start for his 2013 season. Ivory's first 100 yard game came in Week 6 of the 2013 season.
This summer during camp, Ivory was rested due to concerns over his hamstring.
“I wouldn’t say I struggled with injuries in the NFL,” Ivory told the New York Post last summer (NY Post, August 2013). “I had four or five hamstring injuries and a foot injury, which is a lot, but I was always able to get over the hump [in New Orleans] ... it’s always been more the media saying I was injury-prone, which is frustrating."
Since this is preseason, the Jets might be acting very cautiously and not risking making Ivory's injury worse. It is hard to know how serious the injury is at this point -- we don't expect Rex will give many details on the injury after the game.
While we aren't yet worried about whether this will impact the regular season, what's most troubling is the durability of Ivory.
Chris Johnson might be the team's number one runner and with Powell also out with a hamstring injury the Jets are going to want to keep their three top running backs as nick-free as possible. While we're sure that the Jets are going to want to give their runners experience with their offensive line, expect the coaching staff to use their fourth and fifth runners extensively over the next three preseason games.
