The media was allowed to watch training camp for the second time during OTAs Tuesday. The first came last week.
Here are some news and notes from Tuesday afternoon's session at the team's practice facility in Santa Clara:
The Sacramento Bee reported Patton hurt his foot in Monday's session and is awaiting a CT scan. Johnson also missed last week's session open to the media and Jim Harbaugh said Johnson "had a little something that he's working through."
Those absences allowed Josh Johnson, the quarterback, to get some run at receiver. In a red zone drill he made a touchdown catch on a pass from McLeod Bethel-Thompson while being covered by rookie Dontae Johnson.
It also allowed for another big day for Brandon Lloyd, who continues to be the surprise of the offseason thus far. He made a number of catches and is playing much faster than one would expect from a guy that was out of football in 2013. It's still very early in the process, but it looks like the 32-year-old would be a difficult player to cut should he keep performing at this level in training camp.
There isn't much need for Crabtree and Boldin to work every day. These workouts are voluntary. The mandatory minicamps aren't until June 17-19.
—Vernon Davis and Alex Boone were still away from the team presumably because they are looking for new contracts. Davis' absence has allowed for Vance McDonald to take more reps while the team is able to get a better look at Garrett Celek, Derek Carrier, Asante Cleveland and Kevin Green.
—Blake Costanzo returned to the field after spending the last two seasons with the Chicago Bears. Fans will remember him as one of the key members of the "Tony Montana Squad" that riled up crowds at Candlestick prior to covering kickoffs with its dancing to Future's "Tony Montana."
Costanzo gave the impression following practice that he was brought in primarily to work on special teams and not necessarily get involved in the heated competition to back up NaVorro Bowman.
"Whatever role they want me to do I'll do," Costanzo said. "Obviously I've been a special teamer my whole life so I'm definitely going to focus on that."
—Ian Williams admitted his broken ankle suffered in Week 2's loss in Seattle last season required four surgeries. He described his foot as "dangling" from his leg when the injury happened. He said along with the broken bone, he tore ligaments in the ankle. Two of the surgeries were to put in pins and a plate while the last one in February was done in order to prevent an infection.
Williams added he plans on being 100 percent for training camp and that the biggest issue is getting strength back in his lower leg. Playing nose tackle, he said, makes it more difficult to come back from an ankle injury because he often has to create angles for his teammates by taking on two blockers at once.
—It looks like newcomer Chris Cook is transitioning well to his new team. After struggling for much of his career with the Vikings, he has been working with the first unit opposite Tramaine Brock. That will likely change when Chris Culliver returns to full participation, but Cooks' reps are significant because he's getting them over a returning player in Eric Wright. Perrish Cox and Darryl Morris continue to get the majority of the reps at nickel.
Culliver saw some reps with first team initially, but spent most of his practice doing strength and conditioning drills with a trainer.
"I could be out there (playing) now," Culliver said. "But like I said, I'm not in a rush to be doing every single thing. Just taking my time. We have a good game plan."
—The 49ers have one more voluntary OTA session this week occurring Thursday. They have more next happening Monday, Tuesday, Thursday and Friday.
