New Orleans Saints safety Kenny Vaccaro will begin serving his four-game suspension and will miss the four remaining regular-season games of 2016, Coach Sean Payton confirmed at his Friday press conference.

The Saints (5-7) play at the Tampa Bay Buccaneers (7-5) on Sunday at 3:25 p.m. The Saints close out the regular season at the Arizona Cardinals, vs. the Bucs at home and at the Atlanta Falcons.

Payton also announced that tight end Josh Hill has been placed on injured reserve and that the team had signed linebacker Travis Feeney off of the Pittsburgh Steelers' practice squad.

Payton said Vaccaro, who was suspended for a violation of the league's performance-enhancement policy, had decided to serve the suspension now so it wouldn't carry over into next season. Vaccaro has played in 11 of the team's 12 games this season with 68 tackles, one sack, two interceptions, two forced fumbles and one fumble recovery. The 6-foot, 214-pounder is in his fourth season out of Texas. The former first-round draft pick started all 11 games this season and 55 in his career.

Following is a statement from an NFL spokesman:

"Kenny Vaccaro of the New Orleans Saints has been suspended without pay for the team's next four games for violating the NFL policy on performance enhancing substances.

"Vaccaro's suspension begins immediately. He will be eligible to return to the Saints' active roster on Monday, January 2 following the team's January 1 game against the Atlanta Falcons."
