Jaguars' Mychal Rivera: Could be released

Rivera (wrist) isn't a lock to make the Jaguars' final roster, Ryan O'Halloran of The Florida Times-Union reports.

Rivera hasn't practiced since Aug. 1 and is set to miss the entire preseason, putting his Week 1 availability in serious question. The extended absence could impact his role even if he stays with the team, as he hasn't had an opportunity to prove that he's deserving of a key role in the offense. The team doesn't have a proven pass-catching option at tight end to complement 33-year-old starter Marcedes Lewis.
