Following a loss to Desmond Green for the Titan FC featherweight title, former UFC competitor Steven Siler has decided on a career change.

Siler is dropping down to the bantamweight ranks for his next fight with Titan FC. He lost via decision to Green this past weekend.

“Well it’s that time, I realize I’m too small for 145,” Siler posted on Twitter recently. “Next Titan fight I’m ready for 135.”

Siler (23-14) has lost each of his last four fights, including Octagon defeats at the hands of Noad Lahat, Rony Jason and Dennis Bermudez. During his UFC run, he defeated Mike Brown, Kurt Holobaugh and Cole Miller, going 5-4 overall.
