The 32-year-old 'That 70s Show' star will feature as an agent in the season fourteen of the dramatic police procedural television series.
"Thrilled to be joining @NCIS_CBS.. We are gonna have some fun.. And expect the unexpected.. #NCIS @CBS hope you guys are ready," Valderrama tweeted.
The "Minority Report" actor will play a once-grounded NCIS field agent, who accepted a deep cover assignment years ago and never returned, reported Aceshowbiz.
Valderrama will get into the shoes of original cast member Michael Weatherly, who left the series after 13 years.
