The 49ers may sign a wide receiver for the playoffs. Joe Hastings will likely play in Sunday's regular season finale, but the team has been in contract with at least one former NFL wide receiver they may be interested in signing. After wideout Joshua Morgan suffered a broken leg that ended his season, San Francisco worked out a group of wideouts that included Hastings and NFL veterans Brian Finneran, Chris Chambers and T.J. Houshmandzadeh.
