SANTA CLARA -- The 49ers on Friday waived injured offensive tackle Luke Marquardt, a source said. Marquardt spent his rookie season on the non-football injury list, but had been taking part fully in the 49ers' offseason program until last week.
Marquardt fractured the same foot that required surgeries and kept him out of action in 2012 and '13, a source confirmed a report from the Sacramento Bee. If Marquardt clears waivers, as expected, he will automatically revert back to the 49ers' injured reserve list.
The 49ers have yet to make a corresponding move to fill the open spot on their 90-man offseason roster. Fifteen players are currently seeking contracts from the 49ers, as they attend the team's rookie camp this weekend on tryouts.

Marquardt signed with the 49ers last May as an undrafted free agent from Azusa Pacific, where he played in 30 games with 25 starts in his career. He missed his final season with a foot injury. He was never healthy enough to take part in any football activity last season with the team.
The 49ers paid Marquardt a practice-squad salary of $6,000 a week during the season while he was on the non-football injury list.
A former basketball player, Marquardt (6 foot 8, 315 pounds) caught the attention of the 49ers with his size and athleticism.
