Notre Dame quarterback Brandon Wimbush is healthy, but linebacker Greer Martini is “day-to-day” with a knee injury as the No. 13 Irish prepare for No. 11 USC. Wimbush missed Notre Dame’s last game on Oct. 7 at North Carolina because of an injury to his right foot. “There are no questions about his health,” Notre Dame coach Brian Kelly said of Wimbush on Tuesday. “We can put that to rest in terms of how is he. He’s 100 percent. There are no health issues at all.” Wimbush has completed 69 of 132 passes (52.3 percent) for 782 yards, six touchdowns and two interceptions. He also has rushed for 402 yards and eight touchdowns. “He continues to grow and develop as a quarterback that is going into his sixth start,” Kelly said. “He’s been really productive in a number of areas for us. Moving the chains, fourth-down conversions, third down, big plays.
