Fans will see even more of Luke Mitchell as Lincoln Campbell in “Marvel’s Agents of S.H.I.E.L.D.” Season 3 as the star joins the regular series cast!

Though Alphonso “Mack” Mackenzie (Henry Simmons) almost quit the organization at the end of last season, Coulson eventually got him to change his mind—and it looks like now he’s sticking around for good!

Simmons is now the latest star to join the regular cast of “Marvel’s Agents of S.H.I.E.L.D.” for Season 3 when it returns to Tuesdays on ABC this fall, following quickly after the word that Luke Mitchell will also become a regular part of the series.

"Marvel’s Agents of S.H.I.E.L.D." returns for a powerful third season introducing new friends and foes inspired by the critically acclaimed SECRET WARRIORS comic series. In the aftermath of S.H.I.E.L.D.’s battle with Jiaying and the Inhumans, Director Coulson will search the world for more powered people and assemble an extraordinary new team to deal with threats unlike the world has ever seen. However, the Agents of S.H.I.E.L.D. will soon find out they're not the only ones tracking down these new Inhumans.
