At 6'5" and 277 pounds, Smith enjoyed a nine-year professional career, beginning with a two year stint--from 1987 through 1988--with the Dallas Cowboys. After that, he spent a year with Cleveland and two years with Philadelphia, before departing for the CFL, where he spent the final four years of his career.
Smith played his college ball at the University of Tennessee.
The cause of death has not yet been revealed. Smith was checked into the hospital in the early morning hours of Thursday, February 11 with pancreatic problems and gall stones; he reportedly slipped into a coma shortly thereafter, and was pronounced dead around 5:30 AM, local time.
