Financial terms of the deal are not yet known, though it will surely pay him less than the $8.5 million he was initially set to make before he was cut. Rice is recovering from a torn ACL in October, but has been cleared to return to football activities.
Brown finished third on the team in receiving yards a year ago, finishing with 32 receptions for 446 yards and a pair of touchdowns in 11 games.
Sanders is expected to replace the departed Eric Decker, and Manning said they have a lot of work to do.
"I'm excited about playing with him," Manning said.
Floyd continues to recover from a neck injury suffered in September. His participation in the offseason workouts will be more limited than most of his teammates, according to the report.
The report also added that no decision has been made whether Floyd will be able to continue playing. For weeks, Floyd has been running and lifting. While the injury did not require surgery, it demanded a long recovery. Risk of re-injury will be assessed before any decision about Floyd's return to the field is made.
As the website noted, Moore caught at least 50 passes and six scores in four of the five years he played at least 14 games with New Orleans. Both of those numbers should be attainable for Tate in Motown.
Ultimately, Tate is excited about fitting his skills in with what's being asked of him.
"Here we have our rules, initially, to learn the offense, but at the end of the day you have to play football," Tate said. "I think that's what I do best. Just finding ways to get open. Although a route is supposed to be at 15 yards, sometimes you're going to get pressed and your mental clock tells you to break it down to 12 (yards) and it'll time up correctly. I'm a mental clock kind of guy. In some instances it's going to be backyard football, find the hole and make a play, make a guy miss and go score with it. I see my game really fitting into this offense really well."
Tate has emerged into one of this year's hottest breakout candidates and a borderline No. 2 Fantasy receiver. Expect him to get taken between Rounds 5 and 7 depending on league size and scoring.
Byrd has played in four games over two years with the Cardinals, landing one catch for 8 yards.
The 49ers are locked in with their top two receivers in Michael Crabtree and Anquan Boldin, and Patton is expected to be No. 3 on the depth chart. After that, the 49ers are wide open, and Lloyd could be No. 4 ahead of Baldwin and Osgood.
The report says if Lloyd makes the team Baldwin will likely be out. The team re-signed Osgood this offseason because he is a huge part of the special teams. But the 49ers will likely not keep more than six receivers.
Patton, who finished the season strong in 2013 as a rookie, should have time to develop as the No. 3 option. The 49ers are also expected to take a wide receiver in the draft.
McCown said in an interview with CBSSports.com that he's worked with some top-notch receivers in his career -- Larry Fitzgerald, Anquan Boldin, Steve Smith, Brandon Marshall and Alshon Jeffery -- and Jackson is "right there with those guys."
"I'm very, very impressed with him," McCown said. "You know when you have one of those special guys. You can tell the first time you work with him, you see it and feel it. That was the case throwing with Vincent. You can see why he's been so good for so long because of his work ethic and his attention to detail."
Wilson is expected to be Chicago's No. 3 receiver this year behind Marshall and Alshon Jeffery, and Marshall said in an interview with CBSSports.com that Wilson has worked hard this offseason. The trio of wide receivers have trained together in South Florida to get ready for this year.
"I really want to talk about Marquess Wilson," Marshall said. "He came down and trained with us the whole offseason. We're really looking for him to do some big things. This guy, he's probably the steal of the draft last year. I'm going to say that. He came in, he put in the work, he looks like a body builder. Fast, strong, explosive. I'm looking forward to seeing him in OTAs."
Wilson, who is 6-foot-4, 184 pounds, was drafted in the seventh round out of Washington State last year. He only had two catches for 13 yards as a rookie, but he will now replace the departed Earl Bennett in three-receiver sets.
