With Bucannon out, sophomore Taylor Taliulu took over at the starting strong safety position for the remainder of the afternoon.
The big storyline of the day, though, was the series of scuffles that broke out.
The most surprising was a tussle between freshman walk-on receiver Willie Roach and fourth-year junior quarterback Connor Halliday.
The normally mild-mannered Halliday became irate with Roach, who had a tough time catching the ball. The two exchanged a rather assertive head-butt, followed by some misfired fists and a skirmish that was promptly broken up. Receivers coach Dennis Simmons grabbed Halliday and receiver Henry Eaddy grabbed Roach and threw him to the ground.
That wasn't the only confrontation.
Running back Leon Brooks and receiver Gabe Marks got into it with the linebacking corps after a couple stout hits at the sideline. Marks also got into it with some of the defensive backs toward the end of practice, though no punches were thrown.
Marks deemed it all part of the game.
"When you see the same guys every day, dueling guys in the weight room, it gets to you," Marks said. "It's like having a little brother. The littlest thing can set you off. All good though, it just adds to the competition."
Head coach Mike Leach was unavailable for comment after practice.
As for action between the lines, Halliday and Austin Apodaca looked strong in full-squad scrimmaging.
Halliday connected with junior Isiah Myers on a 10-yard touchdown toward the end of his reps, and Austin Apodaca connected on a 70-yard bomb to Marks on a blown coverage.
Both quarterbacks efficiently moved the ball.
On defense, junior BUCK Ivan McLennan was back running with the 1s. The JC transfer finds himself out of position at times, but brings high intensity every snap.
"Oh man, the BUCK position is a fun position," McLennan said. "I'm getting better and better. We're just competing for that position."
Defensive coordinator Mike Breske said with junior Logan Mayes out for the spring with an undisclosed leg injury, McLennan and freshman Kache Palacio are battling for BUCK playing time.
Breske also noted that Mayes will play some defensive end this season – a position where he started two games last season.
McLennan, who checks in at 6-4 and 238 pounds, said he has packed on almost 30 pounds since arriving in Pullman in January.
"I feel like I should have been this weight (while playing JC ball)," McLennan said. "Sometimes I had to eat (just) a sandwich or a Cup-O-Noodles (for the day). Just the convenience of food … I feel like I have more power to me."
