Shawn Stockman of the R&B group Boyz II Men has been diagnosed with the illness, fellow group members Wanya Morris and Nathan Morris told CNN.

The pair said Stockman was unable to accompany them to Atlanta on Tuesday for a scheduled performance at the 2009 Soul Train Awards.

"We tour eight months out of the year, and we are always traveling around," Nathan Morris said. "It's hectic for us always being in airplanes and airports. He got sick, and it hit him pretty hard."

The Grammy-winning and platinum-selling group, known for their No. 1 singles "End of the Road" and "I'll Make Love to You," has a new album out in stores in November called "Love." Wanya and Nathan Morris still planned to perform at the awards show as a duo, according to the group's manager.

"We go all over the world really, so I am surprised it hasn't happened earlier, to be honest," Nathan Morris said. "I talked to [Stockman] today, and he is doing much better."
