Indianapolis Colts rookie wide receiver Phillip Dorsett fractured his left ankle Sunday and is expected to miss four to six weeks, sources told ESPN NFL Insider Adam Schefter.

Dorsett injured the ankle during the first half of the Colts' 27-21 loss to the New Orleans Saints. Tests on Monday should indicate the timeline of Dorsett's recovery.

He has tallied 10 catches for 159 yards and a touchdown this season.

The Colts selected Dorsett with the 29th overall pick in the first round of this year's draft.
