Jaguars' Mychal Rivera: Won't play Thursday

Rivera (wrist) has been ruled out for Thursday's preseason game against the Panthers, Ryan O'Halloran of The Florida Times-Union reports.

Rivera has yet to appear in the preseason for the Jaguars. The wrist injury has prevented Rivera from sewing up the No. 3 tight end gig, and if it lingers into the upcoming week, his roster spot could be in jeopardy as well.
