The second leg of Van Halen [ tickets ]'s reunion tour has hit a speed bump, with the classic rockers postponing a pair of concerts.

Fans who were planning to see the group tonight (2/22) in Charlottesville, VA, will have to wait, as will those who thought they'd be catching the band Monday (1/25) in Duluth, GA. Tickets for the originally scheduled concerts will be valid on makeup dates that will be announced soon, according to organizers.

No explanation was given for the postponements, and, at press time, a spokesperson for the group had not responded to a request for more details, but weather reports in Charlottesville call for freezing rain tonight, and the postponement of Monday's show in Georgia means the band now has 10 days off before returning to the stage for their next gig, which is set for March 3 in Dallas.

Meanwhile, the group continues to add more shows to its schedule, and, since last check, has tacked a trio of April dates to the end of its itinerary (shown below), including stops in Oakland and Sacramento, CA; and an April 19 concert in Las Vegas as part of golf legend Tiger Woods' annual Tiger Jam benefit event.

"Tiger Jam XI will be incredible with Van Halen," Woods said. "I'm thrilled to have this amazing group of diverse musical talent coming together for such a great cause. Van Halen is one of my favorite bands, and I can't wait to see them perform on the Tiger Jam stage."

More information about Tiger Jam is available at the event's website.

After lying dormant for much of the past decade, Van Halen hit the road last fall with original frontman David Lee Roth at the helm for the first time in 22 years. The group's 2007 tour comprised 39 shows, during which the band raked in $56.7 million. That number earned the group the No. 5 slot on concert-industry trade-magazine Pollstar's 2007 year-end list of top-grossing tours.

Van Halen's set list on the current tour has remained the same throughout the run, and is comprised entirely of songs that originally appeared on the band's 1978-1984 Roth-era catalog. The band hasn't released a new album of original material since 1998's "Van Halen 3," which featured short-lived frontman Gary Cherone. A 2004 best-of set featured three new songs with former singer Sammy Hagar.

The group's future plans beyond the current tour are unknown.
