JACKSONVILLE, Fla. - The NFL suspended Jaguars receiver Justin Blackmon on Tuesday for the first four games of the 2013 season for his second violation in less than a year of the league's substance-abuse policy.

He will not get paid for the four-week hiatus. Maybe more importantly, the suspension triggers language in his contract that voids future guarantees. Jacksonville could cut him without having to pay about $10 million that remains on a four-year, $18.5 million contract.

"Justin realizes he's at a crossroad, not only in his career but in his life," general manager Dave Caldwell said.
