49ers open joint practices with Raiders; Observations from day 12 of training camp

Here is what stood out from the 49ers twelfth day of training camp.

Thursday was the first of two joint practices for San Francisco in Las Vegas with the Raiders.

Brock Purdy

Purdy had some good and some bad during his first action against a different team.

After opening practice with a short throw to Willie Snead while on the move to his left, Purdy took a shot downfield off play action to Deebo Samuel for a gain of 20.

The next reps for Purdy came in a redzone session. He missed Brandon Aiyuk on a slant to the left side but bounced back with a short completion to Ty Davis-Price. On the following play, Purdy hit Christian McCaffrey in the left flat for a touchdown.

Purdy opened a move the ball session with a completion to Brandon Aiyuk on a deep out to the right side. The velocity needed to throw a deep out makes this a good demonstration of Purdy’s arm strength following UCL surgery to his throwing elbow during the offseason.

Following the solid throw on first down, Purdy missed on his next one. Trying to get the ball over the middle to McCaffrey, the quarterbacks throw was off the mark and Raiders defensive back Marcus Peters came away with an interception.

Purdy and the 49ers first team offense finished up their practice by having one shot to move the ball in a hurry up situation.

A couple of completions to Jauan Jennings, a short checkdown and completion over the middle picked up 18. Purdy followed up with misses to Jennings and McCaffrey leaving the offense facing third and ten. The quarterback was able to convert when he found Deebo Samuel on a curl to the left side for a gain of 12. Another 12-yard completion followed, this one to Ross Dwelley over the middle. From there the possession stalled. Purdy was forced to spike the ball on first down to stop the clock, then missed a pair of throws to Jennings to end the possession.

Overall Purdy finished the day 10-17 with one touchdown and one interception.

Trey Lance

Lance had a rough start to the day as a fumbled snap and false start wiped out his first series and he missed badly on two of his first four attempts. Despite the rough start, the completion was a nice one as Lance found Deebo Samuel over the middle for a gain of 15. The other incompletion came on an accurate throw to Khalan Laborn which the running back dropped.

Despite the early struggles, Lance looked sharp while leading the second team offense in a hurry up move the ball situation.

Lance opened the drive with a short completion to Chris Conley. From there he took a deep shot down the right sideline but the throw to Tay Martin sailed long.

Lance then settled in, connecting with Willie Snead, Jordan Mason once each and Ronnie Bell twice. The second connect to Bell was terrific with Lance hitting the rookie wideout with a dart on a deep in route.

The drive stalled deep in the redzone when the Raiders defense forced Lance to throw the ball away on first and goal. With only two seconds remaining, Lance dropped back to pass again. Pressure forced the quarterback out to his left where he fired a shot to Cameron Latu in the endzone. The pass hit Latu in the hands before falling to the ground incomplete.

Lance was 6=12 on the day.

Sam Darnold

Darnold had only three pass attempts during team drills, his lone completion coming on a short throw to Jauan Jennings in the flat while rolling to his left.

The veteran backup completed three of four attempts during a brief seven-on-seven period.

Offensive line

A big question coming into these joint practices was how the 49ers offensive line would look against a different team. The good news is they held up well.

Colton McKivitz and Spencer Burford each looked good while winning their one-on-one reps. The duo followed this up by showing they could handle stunts during a two-on-two session.

It was much the same on the other side for Trent Williams and Aaron Banks. Williams won both reps against Maxx Crosby while Banks looked immovable.

Jauan Jennings

Jennings was targeted a team high eight times on Thursday and brought in everything he as able to get his hands on.

Christian McCaffrey

In addition to catching a touchdown pass from Brock Purdy, McCaffrey had success on the ground. The back was able to slice through and run around the Raiders defense for several big gains.

Defense

The defense practiced two fields away from the media viewing area making it difficult to see much of their action. However, they did move to the middle field late in practice. From there we were able to see them allow a seven-play scoring drive during a hurry up move the ball period.

Former teammate Jimmy Garoppolo hit on six of seven pass attempts and wrapped the drive up with a touchdown throw to Austin Hooper.

Taylor Hawkins

The backup safety intercepted a pass over the middle from Brian Hoyer and took it the other way for a touchdown. Hawkins has been impressive throughout this camp.

Austin Bryant

Bryant blew around the Raiders backup right tackle for a sack of Brian Hoyer.

Ray-Ray McCloud

McCloud suffered a fractured wrist during practice on Monday. The veteran receiver and return specialist will be out for about eight weeks as a result.

Injury Report

Drake Jackson, Robert Beal, Kalia Davis, and Dre Greenlaw all missed practice with hamstring injuries. George Kittle was out due to a thigh injury and Jaylon Moore continues to miss time after suffering a knee injury last week.
