Steelers first-round rookie outside linebacker Jarvis Jones has improved in each week of the preseason. But on Saturday, his evening didn't end with another solid performance, but instead with him heading to the hospital for evaluations on his chest, the team confirmed.

Jones suffered a chest injury during the fourth quarter of the team's game against the Chiefs.

The Pittsburgh Post-Gazette's Ed Bouchette adds that the "Steelers think Jones will be okay," and that the move is "precautionary."

The Steelers used the 17th pick in the April Draft on Jones, after releasing James Harrison  earlier in the offseason.  The team needed to find a pass rusher to fill that void, and Jones fit the build, registering 14.5 sacks, 24.5 tackles for loss, and seven forced fumbles in his final season at Georgia.

After a slow start in training camp, Jones had played well in recent weeks and appeared to be pushing Jason Worilds for the starting job.

Early in camp, Steelers veteran linebacker Larry Foote told CBSSports.com that Jones' path to playing time was simple.

"It's wide open," Foote said of the competition between Jones and Worilds. "In preseason and early in the season, if you're sacking the quarterback, you gotta play. Coach can't keep you off the field if you're sacking. So if Worilds wants to keep Jarvis behind him, you got to sack the quarterback."

Now the hope is that Jones' injury won't keep him sidelined for long.
