The San Francisco 49ers have waived wide receiver Braylon Edwards, with Edwards announcing the news on Twitter:

I was released today by the 49ers due to my injury that required more time to rehab and hasn’t allowed me to re-sync with the offense. I wish the 49ers organization the best of luck during the Playoffs. I will be working hard this off season to strengthen my knee and prepare for the 2012 season. Thanks for your continued support and for being such loyal fans.

Edwards, one of the top free-agent receivers when the lockout ended, caught 15 passes for 181 yards in nine games with the Niners. Edwards hurt the meniscus in his right knee the second week of the season and hurt his shoulder in Week 9. His work habits were a concern, though, with Coach Jim Harbaugh citing his lack of dedication as a reason he didn’t play Dec. 19 against Pittsburgh. The 49ers have yet to replace Edwards on the 53-man roster.
