The Jacksonville Jaguars are unsure over whether or not they will be able to get production from wide receiver Justin Blackmon in 2014.

The 24-year-old is currently serving an indefinite suspension after violating the league's substance-abuse policy for a third time.

"It would be something that would be relatively surprising. Haven't gotten a whole lot of updates from the league [of] where he's at or from Justin, to be honest with you," general manager David Caldwell said, ESPN reports.

The fifth overall pick in 2012 caught 64 passes for 865 yards and five touchdowns as a rookie in 2012, but coach Gus Bradley conceded that he has had minimal contact with him over the past few weeks.
