Indiana quarterback Tre Roberson has left the game against Massachusetts with an apparent left leg injury after running for two touchdowns on Saturday.
Roberson was hurt and left the field in an ambulance after being tackled at the 2-yard line of Massachusetts about two minutes into the second quarter. Earlier, he had run for touchdowns of 50 and 36 yards and thrown a 5-yard scoring pass to Shane Wynn.
He left after rushing four times for 105 yards and completing six of 11 passes for 98 yards.
In his season opener the previous Saturday, Roberson threw for a career-high 280 yards and one touchdown in a 24-17 win over Indiana State.
