INDIANAPOLIS -- Saturday at 4 p.m. ET.

That's the time Indianapolis Colts outside linebacker Robert Mathis' NFL-imposed four-game suspension begins.

No communication with anybody in the organization. No access in the team's facility. No access in the stadium.

Mathis, who was suspended for violating the NFL's drug policy, cannot have any ties to the franchise again until Sept. 29.

Nada. Nothing. Zilch.

"Zero. Zero. Players, coaches, nobody," Colts coach Chuck Pagano said. "I got a memo, a laundry list of dos and don'ts on it. There's more don'ts than dos. That's including you guys, so if you have his cell, burn it."

Mathis' first game of the 2014 season will be Oct. 5 against the Baltimore Ravens. He has not played in any of the team's preseason games and won't play against Cincinnati on Thursday.

Mathis has to work out on his own to stay in the best shape possible so that he can jump right back into the lineup once he returns.

"We've made plans for Robert," Pagano said. "He's going to have a routine. He's going to have a regimen as far as working out, weight room-wise, conditioning-wise. Football, he's got to continue to hone and develop his skill set. There's people out there that will work with Robert and he can go out and hire whoever he wants to hire.

"He's got a regimen from his position coach from a drills standpoint. We can't have him come back in Week 5 for Baltimore and we're starting from scratch, so to speak. I know Robert and everybody in this building knows Robert will stick to that plan and be ready to roll once he gets back."
