The NFL trade deadline is fast approaching this Tuesday, and the San Francisco 49ers have three players in Alex Boone, Joe Staley and Vernon Davis that reportedly could be traded before the deadline, according to Jason La Canfora of CBS Sports.

Teams have reportedly been calling about tight end Davis for weeks, and its unclear if the team will make a move with their star tight end. Davis has stated that he would be highly disappointed if he were traded but understands the nature of the business. The 49ers reportedly had a confrontation between Davis and offensive lineman Staley over Colin Kaepernick this past week, and it will be interesting to see if the team moves one of them before the deadline.

Davis is an unrestricted free agent after this season, but a playoff bound team may still want to take a chance for him if they are lacking a strong tight end. While Davis is likely the hot commodity, some teams have reportedly shown interest in guard Boone.

Boone is in his sixth season in the NFL, and teams struggling with their offensive line could reach for him at the right price. While Boone seems more likely to be traded, NFL executives have reportedly been wondering if the 49ers would be interested in trading tackle Staley. The 49ers tackle is in his ninth season in the league and is one of the best at his position. It would likely take a lot to get San Francisco to trade Staley, but they are 2-5 on the season and clearly need pieces for the future.

While it's uncertain if the 49ers will trade anyone before the deadline, they have three pieces that teams are interested in and could be the team most likely to make a trade before Tuesday.
