Brock Purdy rests, Sam Darnold excels

SANTA CLARA — The 49ers returned to practice after their first day off at training camp but Brock Purdy was not among those participating. Here is Sunday’s roll call:

BROCK PURDY

The Purdy Plan is for him to practice two consecutive days, then not throw the next two days, hence his absence from Sunday’s drills even after a day off. The 49ers typically are planning three consecutive days, so Purdy is limited to individual conditioning (see: running on the side) when not practicing. “That’s why it’s perfect for him,” coach Kyle Shanahan said.

Purdy, the incumbent and presumptive starter, was 3-of-10 Thursday and 6-of-12 Friday in team drills. “He’s done great. Had no arm troubles. He’s getting all this timing back,” Shanahan said. “I was really impressed with him in those two practices. He’s deliberate in everything he does.”

Camp total: 9-of-22

TREY LANCE

He opened Sunday taking the first-team reps, and his first throw was on the money to George Kittle for a 25-yard completion against linebacker Marcellino McCrary-Ball.  Once the 49ers got into their first red-zone drills of camp, Lance entered with the second-string; he found Chris Conley near the goal line, then, on the next snap, Lance scrambled to the left corner for a would-be touchdown. On the next red-zone sequence, Lance got first crack with the starters (left tackle Trent WIlliams and running back Christian McCaffrey rested, per camp protocol so far). Lance’s first throw in that encore went to Conley a touchdown (while Kittle also was open on the other side of the end zone). Lance then overthrew Deebo Samuel, and his final attempt got knocked down at the line by Kerry Hyder Jr.

SAM DARNOLD

This was Darnold’s most impressive day in a 49ers uniform (at least in front of the media). He went 8-of-10 in team drills, and here is the marquee stretch from team drills:

*Darnold stays in the pocket as it collapses and throws a strike over the middle to Brandon Aiyuk, who was covered by D’Shawn Jamison.

*Jordan Mason runs, only to get stripped of the ball by Curtis Robinson, who recovered the fumble.

*Darnold beats a blitz and finds Aiyuk over the middle for a 50-yard touchdown — the FIRST TOUCHDOWN of camp. Aiyuk breaks past cornerback A.J. Parker, races 40 yards after the catch toward the end zone, leaps as he cross the goal line and throws the ball at the wall in celebration.

*Darnold replays that by completing a strike to Deebo Samuel, about 5 yards deeper than Aiyuk, and Samuel races to the end zone.

What has Shanahan learned about Darnold over four practices?  “Very talented guy. The team loves him. He’s doing good things out there and he’s getting more and more comfortable each day,” Shanahan said.

Camp total: 16-of-25

BRANDON ALLEN

Grilled over why Allen is getting an ample amount of reps while Lance and Darnold have rotated some in camp, Shanahan replied that Allen “earned them in OTAs, did a good job.” That said, things could change once four quarterbacks are on the floor, so to speak. “It’ll bump down when we get four out there,” Shanahan said. “It’s exciting to put pads on (Monday) and play more football. It’s about 30 days away (from roster decisions). We’ll see how it unfolds.”

Allen went 3-of-5 on Sunday, including a touchdown strike to (who else?!) Aiyuk, and he closed with a touchdown toss in the front corner to Ray-Ray McCloud. Allen again missed deep, this time to Tay Martin.
