Jacksonville Jaguars wide receiver Justin Blackmon has messed up again. He was suspended indefinitely by the NFL for violating the league's subtsance abuse policy on Friday. He was already suspended for the first four games of this season, for previously violating the policy.

"I want to sincerely apologize to Mr. (Shad) Khan, my teammates, my coaches and to the Jaguars fans for not utilizing the resources that I was provided to overcome my challenges," Blackmon said in a statement released by his agent. "I am determined to overcome the issues that have resulted in this situation, and I truly appreciate the support that the Jaguars and my agent have shown me. I will address these matters with the type of intensity I usually direct toward my on-field play so that I can be ready to be a productive member of the team and community next season. Again, I am truly sorry to Mr. Khan, my teammates and coaches and to the Jaguars fans for the impact of my situation on the team as well as to my family and friends and those that have been there for me during these challenging times. Nobody is more disappointed with all of this than me."

Blackmon has a history of substance troubles. He was arrested for misdemeanor DUI in Texas back in 2010, and then arrested again for DUI a month later in Oklahoma. This latter arrested landed him in the NFL substance abuse program.
