The Cincinnati Bengals have signed Washington State defensive tackle Kalafitoni Pole to a contract, the team announced on Sunday. Aaron Wilson with the Baltimore Sun initially reported that the Bengals had offered him a contract after inviting him as a tryout player for this weekend's rookie minicamp.

The former Washington State nose tackle generated 14 tackles and 1.5 tackles for loss last season. As a Junior in 2013, Pole racked up 28 tackles, three tackles-for-loss, two quarterback sacks and forced one fumble.

The Bengals could develop Pole into a needle-in-a-haystack project, who may have an opportunity to fight for a spot at the bottom of Cincinnati's defensive tackle roster. Behind Geno Atkins, Domata Peko, Brandon Thompson and Devon Still, are development-level players like DeShawn Williams (signed as a college free agent), Marcus Hardison (selected in the 2015 NFL draft) and Kwame Geathers.
