The top of the San Francisco depth chart at receiver is clear.  Beyond the first few spots, there’s plenty of churning going on.

After recently dumping 2011 first-rounder Jon Baldwin, the 49ers have waived Chuck Jacobs (pictured) with the “injured” designation.  Jacobs tore an ACL on Thursday night against the Ravens.

If Jacobs clears waivers, he’ll land on injured reserve with San Francisco.

In his place, the 49ers signed receiver Lance Lewis.  He entered the league as an undrafted free agent in 2012 with Washington, spent plenty of time on the practice squad, elevated to the active roster in 2013, was cut after three games, signed with the Cowboys’ practice squad in late 2013, inked a futures contract after the season, and was cut on May 12.
