Defensive end DeForest Buckner aggravated a low-ankle sprain in the 49ers’ exhibition opener Friday night and is not expected to be available for this week’s game against Denver Broncos.
Buckner originally sustained a left ankle sprain during practice on Wednesday, Aug. 2. He missed three practices. Coach Kyle Shanahan said on a conference call with Bay Area reporters on Saturday that the plan is for Buckner to be held out of practice this week and not participate in the upcoming exhibition game against the Denver Broncos.
"It won't be a long thing, but I'd be surprised this week versus Denver," Shanahan said. "He keeps doing the same thing over and over again. We're going to rest him a bit and let him get fully healthy."
--Safety Jimmie Ward will undergo some tests Sunday and could be available to be removed off the physically-unable-to-perform list this week, Shanahan said. Ward sustained a hamstring injury during the conditioning test at the beginning of training camp.
--Defensive lineman Ronald Blair (groin) is also doubtful for this week’s game, Shanahan said.
--Rookie defensive lineman Solomon Thomas had a positive first game while seeing action on 28 snaps.
"We wanted him to get out there, play some, get his feet wet, get used to the speed of the game," Shanahan said. "By no means was it all perfect, but I think you guys all saw, he definitely got noticed out there and caused some pressure on the quarterback. He ran to the ball and had a big hit on the sideline."
--Rookie linebacker Reuben Foster saw action at both inside linebacker positions. He played 13 snaps at weakside linebacker and 14 snaps at middle linebacker, Shanahan said.
“We have him playing both positions,” Shanahan said. “He did a good job of making the calls. He wasn’t perfect by any means with his alignments and getting in the right gaps, but he showed why we wanted him. He flies to the ball, he’s a square hitter, good tackler, and got a chance to get his hands on the ball. . . . The more he plays, the better he’s going to get.”
--Undrafted rookie Lorenzo Jerome started at safety played 33 snaps, and Shanahan said he did a “solid job.”
--Rookie quarterback C.J. Beathard will not have to wait until the third quarter in the 49ers’ next preseason game to get on the field. Shanahan said it is likely Beathard will be the second quarterback into the team’s next game. Beathard and Matt Barkley are competing for the No. 2 job behind starter Brian Hoyer.
“We haven’t discussed it yet as a staff, but I expect to see C.J. much earlier,” Shanahan said.
--Shanahan had strong praise for defensive lineman Aaron Lynch, who recorded two sacks.
“I was real happy for Aaron,” Shanahan said. “He’s battled his weight this offseason. He came to training camp in as good of shape as I’ve seen him. He’s been doing a good job in practice and you never know if you’re going to get rewarded and how it’s going to play out in a game. But for him to be in the amount of plays he was in (15) and make the number of plays he did, I think he did a very good job.”
