Perry Farrell suffered a setback Sunday night when the Jane's Addiction frontman tore his calf muscle onstage in Atlanta during his reunited band's opening number, 'Three Days.' The injury occurred just three shows into the NIN/JA tour, Jane's ongoing co-headlining trek with Nine Inch Nails and Tom Morello's Street Sweeper Social Club the opener. Despite the pain, Farrell powered on and performed a full set before consulting doctors.

The singer was taken by ambulance from the Lakewood Amphitheatre to Atlanta Medical Center after the show. According to a statement, Farrell intends to perform on schedule Tuesday night in Austin, Texas , although he may be sitting down for upcoming gigs as doctors have ordered him to stay off the leg for several days.

The Jane's/NIN tour got off to a rousing start Friday night in West Palm Beach, Florida. According to reports, Farrell, guitarist Dave Navarro, drummer Stephen Perkins and bassist Eric Avery relied heavily on fan favorites like 'Stop,' 'Been Caught Stealing,' 'Ocean Size,' 'Mountain Song' and one of the band's earliest numbers, '1%.'

Meanwhile, Trent Reznor made a curious remark in between tunes like 'Heresy, a cover of David Bowie's 'I'm Afraid of Americans' and the classic 'Head Like A Hole,' saying "This tour is kind of strange for us because we're going away after this." If fans were miffed that NIN left catalog staples like "Hurt", "Closer" and "The Perfect Drug" off of its playlist, they were probably more disappointed when the band never returned for an encore. On his Twitter, Reznor said the PA was turned off, leading to his first temper tantrum of the tour. Hoepfully all the bands have nothing but smooth sailing from here on out.
