What happened: Notre Dame ruled out team captain and linebacker Drayk Bowen for Saturday's game against No. 1 Miami due to a right ankle injury. Bowen, who leads the Irish with 45 tackles and relays defensive signals, exited during the first half against Navy and did not return. Kyngstonn Viliamu-Asa cleared the injury list following a thumb injury and will start at Mike linebacker, backed up by sophomore Madden Faraimo.

Why it matters: Bowen's absence removes the primary communicator from a defense that leads the country by allowing just 2.14 yards after contact per rush. That unit faces an undefeated Miami offense that averages 47.6 points per game and has scored at least 33 points in each of its first eight contests. While cornerback Leonard Moore returns from a concussion, the Irish secondary remains thinned with DJ McKinney and Brauntae Johnson sidelined.

What to watch: Notre Dame hosts undefeated No. 1 Miami on Saturday, with Viliamu-Asa and Faraimo anchoring the interior defense against the Hurricanes.
