The 49ers had their second practice of a three-day session on Wednesday. The media not only was invited, for the first time since 2010, we were permitted to walk around all three fields instead of being restricted to one spot.

Some observations of the first 25 minutes of the session:

Kap's delivery: One of the critiques of quarterback Colin Kaepernick during the draft process in 2011 was that he had a long, looping delivery. He worked on changing that this offseason, and it was apparent that the 49ers quarterback had altered the motion.

Kaepernick is not getting rid of the ball as quickly as Aaron Rodgers, of course. But he seems to be holding the ball higher and his delivery seems more efficient than it's been. The change in motions hasn't appeared to take any speed off his passes. He was still throwing a 'heavy' ball to his receivers and his zip was notably faster than that of Blaine Gabbert, the only other quarterback on the roster.

Who's here: The 49ers had good attendance at the voluntary session. Notable players not on hand: offensive linemen Alex Boone and Anthony Davis, defensive lineman Justin Smith, receiver Anquan Boldin, fullback Bruce Miller, outside linebacker Aaron Lynch and safety Jimmie Ward.

Boone, who held out last offseason, will not take part in any voluntary sessions this year, a source said. The 49ers' first mandatory minicamp is June 9-11. Boone is entering the final year of his contract and won’t report for any voluntary sessions until he has a new deal.

Miller is staying in his native Georgia until there is a resolution in the investigation in the spousal battery case from last month. Miller was arrested in Santa Clara for allegedly shoving a woman to the ground and smashing her phone but has not been charged.

Among those rehabilitating or working through injuries were defensive lineman Darnell Dockett (ACL), center Daniel Kilgore (leg), nose tackle Glenn Dorsey (?) and receiver Bruce Ellington (?).

Back in action. There also were several players on the practice field for the first time in a long while. The most prominent, of course, was inside linebacker NaVorro Bowman, who was lined up next to Michael Wilhoite when the defense began full-unit drills.

Also on the field was nose tackle Ian Williams, who suffered a broken leg in 2013 and an ankle injury last season.

Observations: When the first-team defense was on the field, the starting cornerbacks were Tramaine Brock and Shareece Wright, which wasn't a surprise. With Ward absent, Leon McFadden was playing nickel cornerback.

Linebacker Shayne Skov looks slimmer than he was last season. The biggest critique about Skov, who played at Stanford, has been his speed or lack thereof. ... Speaking of weight, running back Carlos Hyde said he weighed about 228 pounds. That's not dramatically different than the 232 at which he said he played last season.
