SANTA CLARA -– Right tackle Anthony Davis, who opened his career with 64 consecutive regular-season starts, will see his streak come to an end on Sunday.
Davis was ruled out of the 49ers’ season opener on Sunday against the Dallas Cowboys due to a hamstring strain he sustained in practice last week. He has not missed a start since entering the NFL in 2010 as 11th overall pick.

Coach Jim Harbaugh declined to say how the 49ers would compensate for Davis’ absence, though Jonathan Martin has been the starting right tackle from the offseason program, through training camp and the exhibition games.
Guard Alex Boone will be activated to the 49ers’ 53-man roster and will be eligible to play in Sunday’s game. The 49ers were granted a roster exemption when Boone reported to the 49ers on Monday after an extended holdout. The 49ers must release a player off their roster on Saturday to make room for Boone.
Harbaugh declined to state whether Boone or Joe Looney will start at right guard on Sunday. Boone has also served as the swing tackle the past two seasons.
Wide receiver Michael Crabtree is listed as questionable with a calf strain, but he is expected to play in Sunday’s game.
