It turned out that Jones suffered the same injury that many grade-school children endure on the playground: He had the wind knocked out of him, according to the Pittsburgh Post-Gazette.
"I got tackled from behind, fell on the ball, dude fell on me, knocked the air out of me," Jones said. "I don't know how many fell on top of me."
While the rookie won't have to deal with a nagging injury, he will have to take some heat from teammates.
"He's just going to hear from a lot of guys about how soft he is," said inside linebacker Larry Foote, one of many teammates who initially didn't think the injury was serious.
"It kind of scared me when I saw (the news) going across the TV," Foote added. "But I texted him, and he told me he was fine. I told him they don't make them how they used to make them."
Jones has been dynamic this preseason -- the injury occurred after he intercepted a pass -- and though the rookie might be ragged on by his elders, the veterans know he will play an essential role in the Steelers' success.
