The Journal-Star is reporting that Teeng Akol, a 6-10 (or 6-11, depending on the source) is visiting Lincoln this Monday. Akol was committed to South Florida for this fall, but some sort of eligibilty snafu (which the LJS's Brian Rosenthal likens to the Sallie situation) will prevent Akol from playing at South Florida.
Akol is also considering Oklahoma State, who is also sorely in need of a big man. Akol will be a recruit for this fall (assuming he clears the NCAA Clearinghouse), and will fill the major gap in the Husker's lineup for this fall.
I'll update when more is known.
