he can play without sitting out. If not, he has to sit out a year but can be on scholarship and that year can count as a redshirt year even if he's already redshirted(currently if the school he is leaving doesn't give him a release, he can't be on scholarship the 1st year). If there's truly a medical issue that requires him to come closer to home, most schools in WV's situation would grant the waiver, and even if they don't the kid's not really hurt. Based on what I've read, that his mother was hurt in a car wreck and tried to drive to WV to see him play but decided it was too painful so she quit, the NCAA should grant the waiver if the wreck happened after he signed to play at WV. But if the wreck was before he signed, it depends on if they reasonably thought that driving that far wouldn't be a problem for her at the time he signed.
Another interesting waiver the Bears are trying to get is for the basketball player who transferred to South Carolina, sat out last year, and is now transferring back to Mississippi. I don't think one should be granted.
