LeSean McCoy is their key player and will be a big miss should an ankle injury sustained in the week 17 win over Miami keep him out at EverBank Field. Buffalo could play right into the Jaguars' hands. Without McCoy, the run-first Bills would be forced to turn to Mike Tolbert, shifting a ton of the pressure onto the arm (and legs) of quarterback Tyrod Taylor and creating a much more hard set of circumstances.
ESPN's Adam Schefter reported Saturday evening that McCoy, who is listed as questionable for the game, is likely to play.
But three wins in four to end the season and a bit of help from Cincinnati ended the longest play-off drought in all of USA sport.
The Jaguars took the lead with a 15-play drive covering 86 yards in 8:52.
Rookie running back Leonard Fournette tore Heinz Field up for 181 yards and two touchdowns in a powerful 30-9 victory.
Buffalo had more success (148 yards), but failed to cash in on a first-and-goal opportunity at the Jaguars' 1-yard line.
The two teams, which combined for less than 500 yards total offense in the game, traded field goals late in the second quarter and went into the locker room at the half tied 3-3. But receiver Kelvin Benjamin was called for offensive pass interference in the end zone.
As for the Jaguars, Sunday's playoff appearance is the first since 2007.
Bortles was 12 of 23 for just 87 yards passing, but had 88 years on the ground for the Jaguars, who finished the regular season at 10-6 and were hosting their first home playoff game since January 2008.
