On Wednesday night, we looked at reasons why it appeared the San Francisco 49ers were exploring the wide receiver market in free agency.However, ESPN's Adam Schefter dropped a bit of a bombshell on Thursday. Schefter reported that New England slot receiver Julian Edelman will visit the 49ers on Friday. Schefter also reported the team is interested in Giants receiver Hakeem Nicks.Both players will likely be fairly costly and the 49ers don't have a ton of salary-cap room.
