SANTA CLARA -– Coach Jim Tomsula downplays the importance of the 49ers’ depth chart, but a couple defensive changes were notable during Wednesday’s practice.
In just his second day back to 11-on-11 work, Aaron Lynch lined up at left outside linebacker with the 49ers’ first unit in place of Corey Lemonier. And impressive first-year player Keith Reaser continued to work with the first unit at left cornerback. Reaser has taken over for veteran Shareece Wright, who has lined up with that squad since the opening of camp.
Lynch has been nursing an undisclosed back injury that prevented him from taking part in team work through the first two weeks of training camp.
