Stanley signed with the Baltimore Ravens on May 3, 2013, and was released by the team on May 7, 2013.[4]
Stanley initially joined the San Jose SaberCats as a backup quarterback. Stanley became the starter, however, when original starter Russ Michna was declared out with concussion-like symptoms.[5]
Stanley returned to the SaberCats in 2015, where he again served as backup (this time to Erik Meyer). An injury to Meyer forced Stanley to once again become the team's starter. He returned to the role of backup following Meyer's return. In his second season, Stanley threw a total of twenty touchdown passes (and no interceptions) while winning every game in which he started.
Stanley's SaberCats ultimately advanced to ArenaBowl XXVIII, where they defeated the Jacksonville Sharks 68–47. In the fourth quarter, Stanley was briefly inserted as quarterback for the SaberCats; his lone pass attempt was caught for a touchdown. Stanley became the fourth SaberCats quarterback to throw a touchdown pass in an ArenaBowl (following John Dutton, Mark Grieb, and 2015 teammate Erik Meyer).
On November 9, 2015, Stanley was assigned to the Los Angeles KISS.
On October 14, 2016, Stanley was assigned to the Washington Valor during the dispersal draft.[8] On March 21, 2017, he was placed on refuse to report.[9]
