"I was hoping we would get him," Jackson said Wednesday. "I'm still hoping -- a little bit."
In April, Jackson worked out with Brown, who is the cousin of Ravens first-round pick Marquise "Hollywood" Brown. Jackson later said he would be "happy" if Baltimore signed the seven-time Pro Bowl wideout.
On Wednesday, Jackson reiterated his stance on Antonio Brown.
"We want to win, and I can tell in him [that] he wants to win," Jackson said. "He wants to play ball."
Ravens officials have never shown any public interest in Brown and have repeatedly tried to obfuscate the situation when asked about Brown, never even mentioning him by name in their responses. In April, Ravens general manager Eric DeCosta said he would keep his thoughts about Brown "in-house." In May, DeCosta named every skill-position player on the Ravens roster when questioned about the team's interest in Brown before adding, "We're excited about those guys."
The addition of Brown appears unlikely because it would take a major change in Baltimore's philosophy. Since 2015, owner Steve Bisciotti has said the Ravens would stay away from players with domestic violence in their past. That policy dates back to when running back Ray Rice was cut after a video of him hitting his future wife became public.
A former trainer of Brown's has filed a lawsuit alleging she was sexually assaulted by Brown on multiple occasions. He also was accused of sexual misconduct by an artist who was working at his home in 2017. The NFL has been investigating Brown under its personal conduct policy.
Last week, Brown wrote an Instagram post in which he indicated that he wants to play in the NFL again and urged the league to resolve its investigation.
On Thursday, Ravens coach John Harbaugh said he respected Jackson's opinion but said he didn't expect Baltimore to pursue the idea right now because of the NFL's investigation.
"We'll look at any and every player at all times. Antonio Brown is no exception. I don't even think he's really available to sign right now. So, it's not really a conversation you have until he's available to sign. That's where we stand on it," he said.
Jackson said he's never had a problem with Brown.
"I just feel, around us, he was a great guy," Jackson said. "You don't see anything going on at all. He's a cool, down-to-earth guy. He's passionate about the sport of football."
Jackson was the unanimous NFL MVP last season in leading the Ravens to a league-best 14-2 record. But the Ravens have one of the youngest wide receiver groups in the NFL. Eight of Baltimore's 10 receivers are 25 or younger, and no one is older than 27.
Brown, 32, was the NFL's most productive receiver from 2013 to 2018, leading the league in catches (686), receiving yards (9,145) and touchdown catches (67). But he hasn't played in an NFL game since the New England Patriots released him after a Week 2 victory in Miami in September.
In their throwing session, Jackson was impressed with Brown's work ethic. According to Jackson, Brown lifted weights before and after their workout.
"There's no quit with him," Jackson said. "That's the type of guy we need in our locker room. I feel like the locker room here is different than any other locker room. There's a brotherhood going on. None of that outside noise. It's strictly inside."
