Saints first round draft pick Robert Meachem needs to have his right knee examined for a potential medial meniscus problem after he missed practices Sunday and Monday. Head coach Sean Payton said after Monday's practice that the Saints knew about a possible minor meniscus problem before they drafted the former standout receiver at Tennessee 27th overall. "After his exam I'll know a little bit more, but it started to get to the point where it was hampering him [Sunday afternoon] running," Payton said. "We backed him off yesterday and the same way this morning."
