METAIRIE, La. -- New Orleans Saints safety Kenny Vaccaro will serve a four-game suspension, starting this Sunday at Tampa Bay, because he violated league rules pertaining to performance enhancing drug use, the NFL announced Friday.The league did not specify which banned substance was found in Vaccaros system. The league not only bans steroids, but also diuretics that have been known to mask steroid use, so a positive test for either could have triggered a suspension.The Saints have four regular-season games left, meaning Vaccaros wont play again this season unless New Orleans (5-7) rallies to make the playoffs. The Saints trail NFC South Division leaders Tampa Bay and Atlanta by two games.Saints defensive coordinator Dennis Allen said the Saints were aware of the initial positive test, which had to be confirmed and could have been appealed, so he and his staff had time to develop a contingency plan for this very scenario.Were ready to go out and execute that contingency plan, Allen said. Obviously, when you lose a guy of his caliber, its tough and hard on your defense. Its hard on the football team, but yet its no different than dealing with injuries throughout the season. These things happen and you have to be prepared for them when they do.Vaccaro, a first-round draft choice out of Texas in 2013, was in on 67 solo or assisted tackles this season. He had one sack, five tackles for losses, two interceptions, two forced fumbles, a fumble recovery and eight quarterback hits.His versatility has allowed the Saints to play in a number of three-safety alignments on defense, with Vaccaro playing near the line of scrimmage and covering slot receivers or tight ends -- acting sort of as a hybrid linebacker and nickel back -- while fellow safeties Jairus Byrd and Vonn Bell played deeper and in roles more traditional for safeties.Veteran reserve safety Roman Harper is one player who could be called upon to play more in Vaccaros absence. New Orleans also on Friday signed a new linebacker, Travis Feeney, off of Pittsburghs practice squad.Certainly, anytime you lose a player of (Vaccaros) caliber, it affects how you go about game-planning, Allen said. That is something that, as we went throughout this week and over the last few weeks, it is something that we have had to keep in the back of our mind because you never knew when this was going to occur. It is certainly something that we have had to pay attention to over the last few weeks.Saints had coach Sean Payton said Vaccaro could have appealed, but that it made more sense for him to accept a four-game suspension now, rather than risk having a later suspension that could carry over into next season.---For more NFL coverage: http://www.pro32.ap.org and http://www.twitter.com/AP-NFL Uomo Nike Air Max TN Argento Grigie/Bianche/Rosse .Y. -- The Buffalo Sabres have recalled forward Kevin Porter and defenceman Chad Ruhwedel from the minors as part of a five-player roster shuffle made by the NHLs worst team.

STANFORD, Calif. -- Running back Christian McCaffrey status for Stanfords game against Notre Dame may not be clear until Saturday morning, coach David Shaw said Tuesday.Last years Heisman Trophy runner-up did not play most of the second half of last Saturdays 42-16 loss to Washington State.He got banged up over the course of the game and it didnt make sense to put him back in, Shaw said. We will be cautious with him as with everybody else. I will have no answer until Friday or maybe Saturday.Stanford (3-2) plays at Notre Dame (2-4) on Saturday.After rushing for 436 yards over his first three games, all victories, the junior has been limited to 84 total rushing yards over his last two games, both losses.McCaffrey averages 188.2 all-purpose yards, third in the FBS. But he has not scored a touchdown since Week 2 and has just three on the season.Stanford averaged 2.3 yards per rushing attempt against the Cougars and McCaffreys 35 yards were his fewest since gaining 19 against Californnia two years ago.ddddddddddddThere are a few things we need to clean up to give our running backs a clear running lane, Cardinal lineman David Bright said. We havent been the best offensive line in protecting the passer either. Weve stressed being an efficient offense on first and second downs.Shaw called the play of the offensive line spotty at best, though he did not put the entire blame on that unit.We have been inconsistent one through 11, Shaw said. It looks like the offensive line because we didnt run with any efficiency early in the game and because of the sacks. We all have a hand in it.Game notes WR Francis Owusu, who sustained a concussion against UCLA, needs to pass one final test before hes cleared. ... TE Greg Taboada, OL Casey Tucker and CB Quenton Meeks are also close to returning. ... FB Daniel Marx and CB Elijah Holder remain doubtful.
