Coaches held a draft to split the team into blue and gold squads, but the results are unknown, even to players.
"I'm going to try and go and sneak a peek in there," offensive tackle Tyler Rigsbee admitted.
What is expected is that the Golden Bears will try and work under the most game-like conditions possible, risk of injuries be damned.
"I think we're going to be able to get after it," head coach Jeff Tedford said. "Hopefully we stay healthy through that because if somebody does go down, we may have to scramble a little bit."
Tedford had previously been non-committal to the idea of going live, citing the limited numbers at fullback, tight end and on the offensive line. He added that the physicality could be toned down if something happens during their final practice at Witter Rugby Field on Thursday.
It wouldn't be without precedent to conclude spring by not tackling, as USC did last week.
Regardless, Tedford expressed excitement for the chance to work in front of and interact with fans as part of the campus-wide Cal Day activities. 10 to 15 former Bears now playing in the NFL will be in attendance, a trip to the Sept. 15 road game at Ohio State will be given away, and an autograph session will be held at the conclusion of the workout.
"I hope there is a good turnout," Tedford said. "We're going to have a lot of fan interactive things that are going on throughout the game, so it should be a fun, festive day."
The gates at Edwards Stadium will open at 10 a.m., with the practice starting at 11 a.m. Parking on campus is free, but is expected to fill up quickly.
Yarnway Shaken Up
Aside from those players already ruled out for the spring, Tedford said everyone else should be available Saturday.
That includes running back Dasarte Yarnway, who avoided serious injury after being involved in a car accident last week.
"Thankfully he didn't get hurt badly, but he was pretty sore," Tedford said.
Yarnway, who was driving at the time, was able to practice Saturday and Tedford praised his performance.
"He played some fullback and made some good nice runs," Tedford said. "He has had a quality spring ball."
The redshirt junior could be a contender to move to fullback full time, with redshirt senior Eric Stevens coming back from a torn ACL and a trio of youngsters impressing at tailback.
-Sophomore running back Brendan Bigelow did not practice Tuesday because of a twisted ankle, but Tedford continues to rave about his development.
"A couple weeks ago, he got pretty banged up. His ribs were banged up, but he came back in and kept playing and running hard. He's gotten a lot better through spring," Tedford said.
"They all got a really good look at how fast things move and how they are going to have to fit in right away," Tedford said.
The Bears' fifth receiver in the Class of 2012, Kenny Lawler of Upland (Calif.), was retaking the SAT, Tedford said.
