Jacksonville Jaguars receiver Ace Sanders is facing a four-game suspension without pay after violating the NFL's substance abuse policy, he told reporters Tuesday.

Sanders, a former South Carolina receiver, is entering his second season in the NFL after being a fourth-round draft pick in 2013. He caught 51 passes for 481 yards and a touchdown as a rookie.

This season, Sanders is expected to be the Jaguars starting slot receiver. He also returns punts for the Jaguars.

Sanders admitted to making "mistakes" and told reporters he'll take a leave of absence from the game to seek counsel, though he hesitated to say he'll enter a rehab facility, according to the Florida Times-Union.

"I've decided to go seek help and get that attention," he said, according to the Times-Union. "I should be fine."

Sanders had 45 catches for 531 yards and nine touchdowns in his final season with the Gamecocks. He also returned two punt returns for touchdowns. Sanders entered the draft after his junior season.

"I think I'll come back and be ready to play," Sanders said. "This time I'm taking to get everything in order will be really helpful."

Sanders will be available to return to the field Oct. 5 against the Pittsburgh Steelers.
