ET has learned that Jordan, 33, is "struggling" and "beyond sad" by the death of Boseman. The Black Panther star is at a loss for words and was "rocked" by the news.
Boseman was more than a friend, he was a brother to Jordan. He's currently trying to figure out the best way to honor his co-star's legacy.
His “silence is his pain,” ET is told.
Jordan has not released a public statement since the news of Boseman's death. He starred opposite Boseman in the 2018 Marvel action film as Erik Killmonger, the cousin of Boseman's T'Challa.
"[Michael] had to buy into playing a villain, which he hasn't done, you know, and I had to buy into having the weight of the hero [on me]," Boseman told ET back in 2018. "So it's something that we both had to buy into doing together and to collaborating together."
