The San Francisco 49ers could be facing their first contract issue of the summer.
Right guard Alex Boone is reportedly unhappy with his contract, according to a report by the Sacramento Bee Tuesday.
Boone signed a four-year extension in 2011 before becoming a starter the next season and has been a fixture on one of the league's best offensive lines since.
The problem, in Boone's eyes, could be that his deal is too modest considering his production. He's played at a high level and hasn't missed a start over the last two seasons, but is getting paid an average of $1.635 million a year. In 2014 he is scheduled to count for $2.59 million against the salary cap.
The situation has become complicated on the offensive line, but that's not necessarily a bad thing for the 49ers. Former All-Pro left guard Mike Iupati is entering the last year of his rookie contract and could make big money on the open market next spring. Boone has two years left on his deal.
The 49ers added depth on offensive line this offseason in the form of Jonathan Martin, Marcus Martin (a third-round pick) and Brandon Thomas (also a third-round pick). The team is hoping Jonathan Martin could learn to play guard to add to his versatility as the team's reserve swing tackle.
Marcus Martin will be competing with Daniel Kilgore for the starting center job, but will also learn both guard spots. Thomas will likely spend the year "red shirting" after tearing his ACL in a pre-draft workout, and will likely vie for a starting job in 2015.
The key here is the 49ers will not be lacking bodies along its interior of the offensive line this summer even if Boone elects to hold out of the team's mandatory practices in mid-June or training camp slated to start at the end of July.
