Lavin still in coma, battling pneumonia

Professional BMX dirt rider T.J. Lavin is still unconscious and battling pneumonia, but shows signs of improvement, according to friends. "Things have turned around for the positive. Doctors are tackling the infection and feel that T.J.'s breathing tubes will come out this week," said Lavin's friend Kimarie Hunt of Stay Strong Apparel via Twitter on Tuesday.

Following an MRI on Sunday, no further brain damage was found, but there were still signs of swelling on his brain, prompting doctors to place Lavin back on sedation. Lavin additionally developed a slight fever and pneumonia, which he was administered antibiotics for.

The 33-year-old Las Vegas native suffered bleeding on the brain, a broken wrist and an orbital fracture following a crash during dirt qualifying at the Dew Tour Championships on Thursday, October 14.

Earlier today, Las Vegas area rapper Big B brought his motorhome to the University Medical Center in Las Vegas for Lavin's friends and family to rest in while at the hospital with Lavin.

Lavin rose to fame on the BMX dirt scene in the early years of the X Games. He earned a silver medal in 1996 and a gold medals in 1997 and '99. In the years since, Lavin has remained an aggressive competitor on the Dew Tour Circuit while branching out as a TV host for ten seasons of the "Real World/Road Rules Challenge."
