Andy Janovich’s rookie season officially ended on Wednesday because of an ankle injury, the Denver Broncos announced.

Janovich was put on injured reserve after injuring his ankle in Sunday night’s loss to the Kansas City Chiefs. Denver officials said Janovich likely injured his ankle on the first play, but played through the pain. The ankle injury will require surgery for Janovich, who was already playing through a hand injury in his rookie season.

The former Husker had been used primarily as a lead blocker and special teams player during his rookie season, and had four carries for 33 yards, including 28-yard touchdown run in his first career regular season game. Janovich also had five catches for 44 yards.
