Houston Texans defensive lineman Antonio Smith has revealed that he is not surprised by claims that Miami Dolphins guard Richie Incognito was involved in the harassment of a teammate.

Incognito was suspended indefinitely by the Dolphins after allegations that he made racial slurs and threatening remarks towards Jonathan Martin, causing the offensive tackle to go AWOL from the team.

Smith has also had run-ins with Incognito having been fined for kicking the Dolphins player in 2012, as well as being suspended after a pre-season clash with him this year.

"You are what you are I guess. That doesn't surprise me one bit," ESPN quotes Smith as saying.

The Dolphins are reportedly considering cutting Incognito if the claims are proved to be true.
