Luke Joeckel, the Jacksonville Jaguars offensive tackle, was injured Sunday.
Joeckel appeared to suffer injury in the first quarter against the St. Louis Rams.
It is unclear what the injury was. He was carted off the field.
Also it is unclear is if Joeckel will return.
Joeckel was recently moved to left tackle last week. He was selected second overall in April 2012 by the Jaguars.
