Nikki Bella has a stress fracture in her right tibia, which is why she is on crutches.
Speaking of Nikki, she and Brie have been busy. The sisters were at ESPN's "ESPY" awards on Wednesday night, appeared on NFL AM Thursday and are scheduled for KTLA Morning News in Los Angeles. They're also scheduled to appear on E!'s "Fashion Police." Terrence J interviewed The Bella Twins on the red carpet of the ESPYS at this link.
