Ohio State starting quarterback Julian Sayin is officially out indefinitely after suffering an injury to his right (throwing) arm during the Buckeyes' 19–15 victory over Indiana. This not only impacts team execution, but it also triggered a domino effect on the Buckeyes' NCAAF National Championship odds and teammate Jeremiah Smith's odds to win the Heisman Trophy at Polymarket.

Julian Sayin Injury Update: What We Know
During the fourth quarter of Ohio State's win in Bloomington, Sayin was sacked on a first-and-10 play. Though Ohio State recovered his fumble, Sayin was forced to exit the game. He later returned to the sideline in the closing minutes wearing a sling on his right arm.
Head coach Ryan Day confirmed that the program is preparing for a scenario in which Sayin remains unavailable for both the remainder of the regular season and the postseason. No specific timeline has been provided for his recovery, but the head coach's comments dealt a heavy blow to Ohio State's expectations and to market traders projecting the team's national championship odds.
The injury comes during Ohio State's bye week ahead of their matchup against USC, providing the coaching staff crucial time to restructure the offense and tailor the game plan around true freshman backup Luke Fahey.
Ohio State National Championship Odds After the Sayin Injury
Since the confirmation of Julian Sayin's injury, prediction markets have experienced significant movement across NCAAF contracts.
On Polymarket, the "NCAA Football 2027: National Champion" market saw substantial turbulence at the top. Between October 18 and October 19, Ohio State and Georgia traded places for the lead, but Sayin's injury ultimately tipped the scales in favor of the Bulldogs, who currently hold the top spot with a 17% implied probability.
The Buckeyes remain close behind at 16%, but the slight dip in price triggered by the injury relegates them to runner-up status after holding the lead for several hours.
According to Polymarket, Ohio State's contract continues to lose momentum in a subtle yet steady decline, benefiting the third-place contender on the trading board, the Miami Hurricanes, who currently hold a 15% implied probability.
Jeremiah Smith Heisman Odds: Why the Favorite’s Price Dropped
Sayin's injury echoed across another high-profile contract in the NCAAF ecosystem: Jeremiah Smith's odds to win the Heisman Trophy. Due to the severe blow to Ohio State's roster, his price on prediction markets dropped.
On October 18, Jeremiah Smith traded as the absolute favorite with 52% odds, but his contract has since dropped to 44%, with Yes shares selling at 45 cents. The market doesn't believe Smith is a worse player than he was a week ago. Rather, losing a crucial cog in the team's engine leaves the wide receiver with fewer opportunities to showcase his talent.
There are also structural and historical factors that could dilute the value of Smith's contract heading into the end of the season. The most notable is a natural QB bias: while there are precedent cases of wide receivers winning the Heisman, quarterbacks hold a distinct advantage.
This becomes even more pronounced as the season progresses. If one of Smith's top rivals turns in a strong string of performances, they will almost certainly close the gap on the Ohio State star.
Luke Fahey Takes Over: What Changes for Ohio State
Following Julian Sayin’s injury against Indiana, freshman backup quarterback Luke Fahey takes over under center for the Ohio State Buckeyes.
Coming out of Mission Viejo High School, Fahey brings dual-threat mobility, having posted over 1,500 rushing yards and 19 rushing touchdowns in his prep career. Head coach Ryan Day and offensive coordinator Chip Kelly are expected to lean into more designed QB runs, RPOs, and bootlegs to mitigate pressure and ease Fahey transition to starting quarterback.
Despite Fahey's capabilities, a injury-forced quarterback change always triggers volatility and market repricing.
