After playing college football at Oklahoma State, Toston was undrafted in the 2010 NFL draft and was signed by the St. Louis Rams on April 25, 2010.

He was a finalist for the Old Spice National High School Player of the Year award, and was District 24-4A offensive MVP as well as named all-Greater Houston and included on the Dallas Morning News' top 100 list.

In his junior year he was second string, but rose to the challenge in his senior campaign when Kendall Hunter went down with a knee injury.
