Quantrill (triceps) is expected to return from the 15-day injured list to start Sunday's game against the Cubs at Coors Field, MLB.com reports.

Quantrill was placed on the IL with right triceps inflammation on Sept. 1, one day after he was scratched from his scheduled start against the Orioles. He looks like he'll be ready to return to action in close to the minimum 15 days, and he didn't require a rehab assignment after the Rockies were encouraged by how the right-hander fared during his throwing program. That being said, manager Bud Black suggested that Quantrill will have his workload monitored carefully Sunday, with 70-to-85 pitches floated as a rough estimate.
