A win Sunday night would be a major boost for either the Indianapolis Colts or the Pittsburgh Steelers.

The Colts enter this prime-time matchup tied for first in AFC South with the Houston Texans at 6-5, but Indy currently would earn the No. 4 seed based on tiebreakers. The Steelers also are 6-5, but they currently are on the outside looking in at the AFC playoff picture.

Here's how to watch Colts-Steelers online.

When: Sunday, Dec. 6, at 8:30 p.m. ET
Live Stream: NBC Sports Live Extra
