Washington's rep released a statement to CNN paying tribute to Boseman who died last week at the age of 43 following a four-year battle with colon cancer.
"He was a gentle soul and a brilliant artist, who will stay with us for eternity through his iconic performances over his short yet illustrious career," Washington said in his statement. "God bless Chadwick Boseman."
On Sunday night ABC aired the special "Chadwick Boseman: A Tribute For A King" following a commercial-free airing of "Black Panther."
