In the video, Berry said he would return better than ever, adding, "I'm coming back to change the game."
Berry spoke to the Chiefs in the locker room after the victory last week over the New England Patriots, saying among other things he expected them to carry on without him, as they did in 2014 when Berry left the team late in the season after being diagnosed with lymphoma.
Berry returned to the Chiefs for the start of training camp the next summer.
"Eric's doing good with it," coach Andy Reid said. "I mean, he overcame cancer ... he's fought for his life before. Is he disappointed? Absolutely, big-time disappointed. But at the same time he understands he'll have another opportunity to play. There was a point in his life where he didn't know if he was going to have that opportunity to play or if he would.
"He's going to attack the surgery and the rehab after the surgery I'm sure with a lot of intensity, and he'll be back."
But Berry won't be back this season. Trainer Rick Burkholder said the expected recovery period for Berry is six months.
"That's just a ballpark," Burkholder said. "We know that Eric Berry has done some amazing things in the past."
