Spillman.Boone's contract was set to expire at the end of this season, but the 49ers could have easily retained him as an exclusive rights free agent.According to information obtained by CSNBayArea.com, Boone's deal includes four new years with nearly 7 million of new money, including 2.24 million guaranteed. He received a 1.7 million signing bonus when he signed the deal. The deal runs through the 2015 season.

And in the final year of his deal, Boone is scheduled to make 1.2 million in base salary with another 400,000 possible in roster bonuses. Boone can earn 50,000 in workout bonuses each season.
Boone originally signed with the 49ers as an undrafted free agent in 2009. He spent the entire 2009 on the 49ers' practice.

He has played in every game.The deal was signed on Nov. 23. The 49ers on Thursday confirmed the media reports."We are very pleased with the progress that Alex has made since joining the team in 2009," 49ers general manager Trent Baalke said in a statement.
