John Sullivan probable for opener

EDEN PRAIRIE, Minn. -- Minnesota Vikings center John Sullivan is listed as probable for the season opener in New Orleans on Thursday night, even though he has missed virtually all of preseason with a calf injury.

Sullivan was injured early in training camp and did not play in any of the four preseason games. He practiced on a limited basis this week and the Vikings said Wednesday that he was probable to play against the Saints.

That's a big break for Brett Favre and Minnesota. The Vikings tried second-year man Jon Cooper and veteran guard Anthony Herrera at center in Sullivan's absence to mediocre results.

Cornerback Cedric Griffin and rookie running back Toby Gerhart are questionable with knee injuries. Griffin says he feels ready to go after tearing an ACL in the NFC title game in January.

The Saints, meanwhile, re-signed tight end Tory Humphrey and waived cornerback Leigh Torrence.

Saints coach Sean Payton said his decision to bring Humphrey back and release a cornerback stemmed from his belief that starting cornerback Tracy Porter has recovered enough from a recent bout of left knee soreness to play well against the Minnesota Vikings in both team's season opener Thursday night.

Payton also says starting linebacker Jonathan Vilma is probable for the opener, while reserve running back Chris Ivory and reserve linebacker Stanley Arnoux will not play.
