The team officially changed its name from Oilers to Titans for the 1999 season as they debuted a new stadium, Adelphia Coliseum. Early in the season, McNair was diagnosed with an inflamed disk following the Titans' 36–35 win over the Cincinnati Bengals, and needed surgery. In his stead entered Neil O'Donnell, a veteran who had guided the Pittsburgh Steelers to the Super Bowl four years earlier. Over the next five games, O'Donnell led the Titans to a 4–1 record. McNair returned against the St. Louis Rams, and with McNair starting, Tennessee won seven of its last nine games, good for a record of 13–3 and second place in the AFC Central.
