The senior was knocked out of the second half of Saturday's 39-7 loss to Oregon.</p> Freshman Ryan Mallett will start against the Fighting Irish on Saturday at home in a matchup of storied teams with 0-2 records.</p> "This test will be different than any he's had," Carr said. "But I can guarantee you that he's not intimidated."</p> Carr declined to confirm Saturday's ABC-TV report that Michigan trainer Paul Schmidt said Henne had a lower-leg injury.</p> The senior struggled in his first 1½ games as the Wolverines opened with two losses at home for the first time since 1959.</p> Henne was 12-of-23 for 172 yards with a touchdown and an interception, a pass that sailed into double coverage on the opening drive against Oregon. In the opener, he was 19-of-37 for 233 yards with a score and an interception in Appalachian State territory.</p> Henne connected with Adrian Arrington late in the first quarter against Oregon, giving Michigan a 7-3 lead and tying a school record. It was the senior quarterback's 72nd touchdown pass, tying John Navarre.</p> Mallett started the second half and threw an interception midway through the third quarter. He finished with six completions in 17 attempts for 49 yards.</p> The freshman from Texarkana, Texas enrolled at Michigan in January and participated in spring practice.</p> "That helps a lot," offensive tackle Jake Long said. "It's kind of like he's a redshirt freshman." </p> Copyright 2007 by The Associated Press</p>
