The fan base that was downright giddy after an 0-2 start can now be called euphoric.
The Panthers won a game that was marred for a long stretch by a monsoon, beating the Jaguars, 16-10.
Rookie quarterback Cam Newton cooled off considerably, with his 422 and 432 passing yards replaced by a so-so 158.
Newton completed 18 of 34 passes with one touchdown and no turnovers.
Fellow rookie Blaine Gabbert, in his first start, completed 12 of 21 for 139 yards, a touchdown, and an interception.
Jacksonville led 10-5 at the half. The Panthers scored 11 in the second half, via a field goal, a touchdown pass to Greg Olsen, and a two-point conversion to Greg Olsen.
