After the 49ers reached a contract extension with tackle Anthony Davis through 2019, guard Mike Iupati became the next logical person in line for a lucrative deal.
Iupati and the 49ers have engaged in preliminary contract talks, but there is no deal imminent nor is there a timetable on striking an agreement, a source said Monday morning. Albert Breer of the NFL Network wrote Monday on Twitter that the sides have started contract talks.
Iupati, quarterback Colin Kaepernick, outside linebacker Aldon Smith and wide receiver Michael Crabtree have deals that expire after the 2014 season. Each is in line for a significant pay increase. The 49ers are prohibited, as outlined in the new collective bargaining agreement, from extending Kaepernick or Smith until after the upcoming season. Crabtree sat out the first five games of the 2009 season in a contract dispute after the 49ers made him the No. 10 overall pick.
The 49ers signed Davis to a five-year extension on April 9. The total deal covers seven years at $37.295 million and includes a $7.5 million signing bonus.

Iupati, a first-round draft pick in 2010, figures to command a contract in line with some of the top guards in the NFL. He was named to the NFC Pro Bowl team and a first-team All-Pro. Carl Nicks (Tampa Bay) and Logan Mankins (New England) are the highest-paid guards in the NFL at $9.5 million and $8.5 million annually.
