SANTA CLARA – The 49ers are expected to replenish their linebacker to help the team get through upcoming practices and their final three exhibition games.
The 49ers on Wednesday created two roster spots to sign replacements, as the team designated linebackers Donavin Newsom and Jayson DiManche as waived/injured.
General manager John Lynch said the designation was a formality for Newsom, who will revert back to the 49ers after clearing waivers. Newsom will remain under contract to the 49ers after going on injured reserve.
“He’s doing better each day,” Lynch said. “We’re going to put him on injured reserve. It will come across the wire procedurally as a waived-injured, but he’s going to be on injured reserve. And talking with our doctors, he got great care up here at Stanford. It’s the best thing for the kid. Give him time to really get right. So, (I) had a good talk with him this morning.”
Newsom, an undrafted rookie from Colorado, sustained a serious concussion on Aug. 8 and was taken by ambulance off the practice field to Stanford Hospital. He spent two nights in the hospital as a precaution.
DiManche was signed last week and participated in seven plays on defense and 15 on special teams before sustaining a hamstring injury in the 49ers’ exhibition opener against the Kansas City Chiefs. Newly signed linebacker Sean Porter sustained a quadriceps injury in the game against the Chiefs and has also not been available to practice.
