Morris completed two of five passes for 51 yards with no touchdowns or interceptions in Thursday's preseason win over the Bengals.
Morris played just two series, so it's difficult to glean much from his performance. Veteran backup Scott Tolzien will likely start Week 1 against the Rams with Andrew Luck unlikely to play due to a shoulder injury. However, Morris showed enough this preseason that he could overtake Tolzien early in the season if the latter struggles and Luck makes slow progress in his recovery.
