EDEN PRAIRIE, Minn. (AP) — Minnesota head coach Brad Childress said Wednesday he is not concerned with the trash-talking Twitter tussle going on between Vikings tight end Visanthe Shiancoe and Saints safety Darren Sharper.

Shiancoe and Sharper have been sniping back and forth with tweets for the better part of two weeks, a feud that started when Sharper implied New Orleans would go after Brett Favre's surgically repaired ankle in the season opener in September.

The latest exchange happened when some Vikings visited the Minnesota National Guard on Tuesday. Shiancoe posted a photo of a target used for shooting practice. The target had a picture of Osama Bin Laden saying, "I'm Darren Sharper," with Sharper's No. 42 on his chest.

"Before target practice a soldier suggested a custom target for me," Shiancoe tweeted before posting the picture. "Guess he wanted to start my engine early for the SAINTS game!"

Childress was on the same visit with Shiancoe and said he saw him taking the photos of the target and "knew exactly what was going on." But the coach didn't seem too worried about the cyberspace jawing, saying that "there will be somewhere we will reel it in."

Shiancoe was one of several Vikings veterans who was not at Minnesota's optional practice Wednesday.

Sharper and Shiancoe grew to be friends when they played together in Minnesota. Sharper left before last season to join the Saints, who beat the Vikings in overtime of the NFC title game en route to winning their first Super Bowl. The Vikings and Saints kickoff the regular season on Sept. 9 in New Orleans.

The smack talk has been playful throughout, though Sharper appeared to take exception to the photo of the target.

"Ok homeboy you done went too far, making me out to be something that has brought this country alot of heartache," Sharper tweeted Wednesday. "Imma bust you right under your chinstrap from the first play on. I don't care about the fine. ... Imma do it for the red,white&blue."

"And you'll see me cuz I'll be dressed in black & gold," Sharper tweeted. "Protect your neck that's all the warning you get."
