Niners offensive tackle Luke Marquardt, who hasn't played in an organized game since Nov. 26, 2011, was waived after re-breaking the same foot he injured before his senior season at Azusa Pacific in 2012.

Marquardt, 24, who spent last year on the non-football injury list, will be placed on the 49ers' injured reserve if he clears waivers. Marquardt, who was signed as an undrafted free agent last year, told The Chronicle he began feeling pain in his foot during practice May 14.

He will meet with doctors at Stanford Hospital on Tuesday and expects to have the third surgery on his foot in the past 21 months.

"It's definitely disheartening and difficult to deal with, but God's given me this ability for a reason," Marquardt said. "He's given me this body and this passion. I'm definitely going to give it another go with this foot."
