During the first half of the 1977 season, he led the team to five wins in their first seven games. However, on November 13 of that year, Sipe suffered a season-ending shoulder injury at Three Rivers Stadium against the Pittsburgh Steelers in the second quarter of the team's 35-31 defeat. With Phipps gone to the Chicago Bears, the Browns turned to back-up quarterback Dave Mays, who went 1-3 as a starter. The 1977 also saw a head coaching change as Gregg was fired and defensive coordinator Dick Modzelewski took over for the final game. Sipe came back the following year to throw for more than 2,900 yards and 21 touchdown passes, but the team's overall inconsistency resulted in an 8-8 finish.
