My Morning Jacket has postponed its two sold-out Chicago Theatre concerts due to an injury suffered by lead singer Jim James in Iowa City.

From the band:

"As some of you may have heard we had to cancel our show last evening in Iowa City. We were finishing up the last few bars of 'Off the Record,' and just like any other night we were all having a great time. Jim went to get closer to the audience on his side of the stage, and as he moved forward to step onto the sub-woofer the lights darkened, and he inadvertently stepped off the stage. Upon falling, he suffered traumatic injuries to his torso, and was immediately taken to the hospital. Per the doctor's orders, Jim will be off the road and recovering from his injuries for the next two to three weeks. Sadly, we must postpone the two shows in Chicago on Thursday and Friday until further notice."

Of course, Jim James's benefit performance this evening at Schubas for the Obama Victory Fund has been canceled. According to the Schubas Web site, "Campaign contributors have been contacted by the Obama team."
