Visanthe Shiancoe's return to practice was short-lived.
Shiancoe injured his hamstring in the first week of Vikings training camp in Mankato. He returned to practice in pads in Tuesday's extended practice, but was back on the sidelines Wednesday.
Vikings coach Leslie Frazier said Shiancoe hadn't had a drastic setback, but was sore. And the team, he said, is erring on the side of caution and will not play the veteran tight end in Saturday's preseason game against Dallas.
"We just decided to hold him back a little bit, give him a chance to get a little better with his hamstring," Frazier said.
Shiancoe has yet to play in a preseason game and has not had much practice time to develop a rhythm with new quarterback Donovan McNabb. Frazier admitted it wasn't an ideal situation, but reiterated his belief that having Shiancoe healthy for the regular-season opener Sept. 11 at San Diego was paramount. McNabb, meanwhile, downplayed any potential problems.
"We've been communicating with each other all through camp, each practice, on what I may see, how he may come out of routes and things of that nature," McNabb said.
Herrera to play Frazier said Anthony Herrera would start at right guard Saturday night. Herrera, coming back from a torn ACL in his left knee last November, returned to practice last week.
"We're going to start him, unless we have a setback [Thursday]," Frazier said. How well -- and how long -- Herrera plays will give the Vikings a good idea whether Herrera will be ready to go 100 percent for the regular- season opener. Herrera is expected to play through the first quarter.
