The Jacksonville Jaguars fired Gus Bradley on Sunday, ending one of the least successful coaching tenures in NFL history.

Owner Shad Khan announced the decision following a 21-20 loss at Houston, in which the Jaguars (2-12) blew a nine-point lead in the fourth quarter. Khan considered the move in late October, following a debacle at Tennessee on national television, but opted to keep Bradley for seven more weeks. During that time, Jacksonville lost to backup quarterbacks Tom Savage (Houston), Paxton Lynch (Denver) and Nick Foles (Kansas City).

Bradley went 14-48 in four seasons, the worst winning percentage (.225) of any NFL coach with at least 60 games.

The Jaguars were supposed to be considerably improved this season, time for Bradley’s always-positive approach to pay off with a much-improved roster. Khan spent big in free agency for the second straight year and felt he had all the pieces in place for a playoff push. Even before the free-agent frenzy, Khan said a winning record was “everybody’s reasonable expectation at this point.”

Instead, the Jaguars have lost nine in a row. It’s the longest, single-season losing streak in franchise history.

“I don’t know, really, for anybody in this locker room how much more frustrated you can be,” quarterback Blake Bortles said. “Once again we had all the opportunities in the world, chances in the fourth quarter to score, and we just don’t do it.”

General Manager Dave Caldwell will name an interim coach Monday for the final two games. It’s likely to be offensive line coach Doug Marrone or defensive backs coach DeWayne Walker.

JETS: The team was waiting for results from tests on Bryce Petty’s injured chest before making a decision about who will be the starting quarterback Saturday against the New England.

Petty was scheduled to have a CT scan Sunday to make sure he didn’t have a bruised or punctured lung after being knocked out of New York’s 34-13 loss to the Miami Dolphins on Saturday night. X-rays at the stadium were negative.

Petty was hurt on the first play of the fourth quarter when he got sandwiched by Cameron Wake and Ndamukong Suh as he completed a 28-yard pass down the right sideline to Robby Anderson. He was replaced by former starter Ryan Fitzpatrick.

If Petty can’t play against the Patriots, Fitzpatrick would likely start. Rookie Christian Hackenberg is the only other quarterback on the active roster.
