The 49ers created two roster spaces and a bit of salary cap savings on Monday by placing linebacker Chris Borland on the reserved/injured list and waiving outside linebacker Chase Thomas, who tore his ACL last month.
Thomas bounced between the practice squad and the active roster last season. The former Stanford product played on special tams and finished the season with two tackles. The 49ers used a third-round pick Saturday on an outside linebacker, Eli Harold. He'll join a group that includes Aldon Smith, Ahmad Brooks, Aaron Lynch, Corey Lemonier and undrafted Marcus Rush.
Borland, meanwhile, announced his retirement in March. The 49ers made it official today. The move saves the 49ers about $100,000 against the offseason salary cap.
The 49ers drafted 10 players last week and will add at least eight more undrafted free agents this week.
