Joint Statement from Dr. Tim McAdams, Dr. Neal ElAttrache and the 49ers Medical Staff on Javon Kinlaw

Drake Jackson looks better prepared for his sophomore NFL season, both physically and mentally. The San Francisco 49ers defensive end spoke with reporters this week, and reports of his added bulk were visually confirmed. He estimates he has gained about 13 pounds since last season, and the work continues. His defensive line coach, Kris Kocurek, believes the added weight and better preparation will help Jackson last through the rigors of an NFL season. The coach has seen "significant strength gain" in his young defender. Jackson was inactive for six of the 49ers' final eight games last season, including each of the team's three playoff contests.

They once again have a competitive roster and look to make another run at a Super Bowl championship. Armstead joined Adam Schefter on the ESPN insider's podcast, discussing several 49ers-related topics. New defensive coordinator Steve Wilks Steve Wilks replaces DeMeco Ryans as defensive coordinator. Armstead had nothing but praise for his former coordinator, who left to be the Houston Texans' head coach, but looks forward to working with Wilks. Wilks isn't expected to make any drastic changes in his first season helming the 49ers defense.

It's premature to draw conclusions about a quarterback based on practices in May. That is especially true when you do so based on one practice. The San Francisco 49ers started organized team activities (OTAs) this week, and all eyes were on Trey Lance and Sam Darnold. The two players are battling for that QB2 job behind last season's rookie sensation, Brock Purdy. One could even start Week 1 if Purdy is not healthy enough to do so himself. Lance is coming off a season-ending ankle injury but looks completely healthy now. Darnold is trying to turn his career around after never living up to his high draft status.
