Missouri quarterback Sam Horn is sidelined indefinitely and underwent an MRI exam on Friday, one day after sustaining a serious right leg injury during a season-opening victory over Central Arkansas.

Horn was injured on a quarterback keeper in the first quarter on his first snap of the game. He was later seen sporting crutches and a full-length brace on his leg.

Missouri coach Eliah Drinkwitz said Friday that he is waiting to receive more information.

'It's still a little bit of a wait-and-see game,' Drinkwitz told SEC This Morning. 'We have an MRI this morning, and then we'll know more on what the diagnosis is and the next step toward recovery. He'll be out an extended period of time.'The plan was for Horn and Penn State transfer Beau Pribula to share the workload in the 61-6 win over Central Arkansas.

Drinkwitz said recently he wanted game tape of both players in the opener to dissect before he would name a starting quarterback.

With Horn hurt, Pribula will move forward as the starter after completing 23 of 28 passes for 283 yards and two touchdowns against Central Arkansas. He also rushed for 65 yards and two scores.

The injury is a blow to Horn, who missed all of last football season while recovering from Tommy John surgery. A right-handed pitcher, he also missed the Missouri baseball season but was chosen in the 2025 draft by the Los Angeles Dodgers in the 17th round.

Horn subsequently signed with the Dodgers for just less than $500,000 with the club agreeing he would play football this season and then join the Dodgers following the season.

Missouri's next game is Sept. 6 against visiting Kansas.
