LATROBE _ Outside linebacker Bud Dupree got off to a strong start tonight at Memorial Stadium but he couldn't finish.
"Bud is in the (concussion) protocol," head coach Mike Tomlin revealed at the conclusion of "Friday Night Lights," the Steelers' annual off-campus excursion.
"We'll see where that goes."
Dupree had initially announced his presence with authority in the first practice of training camp held somewhere other than Saint Vincent College. He bettered tight end Jesse James on the second rep of Backs-on-'Backers and then followed that up by going 2-0 against tight end Christian Scotland-Williamson and 2-0 in a couple of subsequent rematches against James.
Dupree was just as impressive in the 11-on-11, live-tackling "Team Run" period. First, he got to running back James Conner for what became a 4-yard loss. Next, Dupree got pressure and helped contribute to an incompletion on a play-action pass from quarterback Landry Jones to James. Finally, Dupree shot a gap and dropped running back Jaylen Samuels for a 5-yard loss.
The Steelers never got to find out what Dupree might have done for an encore.
THE BAND'S BACK TOGETHER: Safeties Morgan Burnett and Sean Davis joined cornerbacks Artie Burns and Joe Haden in the secondary for the first-team defense.
Burnett (hamstring) hadn't done any 11-on-11 work since the first practice of training camp.
Davis had left practice early with a groin injury on Sunday.
MEDICAL FILE: Wide receiver Marcus Tucker (ankle), wide receiver Antonio Brown (quad), tight end Vance McDonald (ankle), outside linebacker T.J. Watt (hamstring) and defensive end L.T. Walton (undisclosed) were among those who didn't practice.
Fullback Roosevelt Nix (undisclosed) didn't participate in 11-on-11 drills.
Cornerback Coty Sensabaugh (back), offensive tackle Chukwuma Okorafor (shoulder) and wide receiver Darrius Heyward-Bey (back/neck) didn't finish practice, along with Dupree.
Quarterback Ben Roethlisberger, center Maurkice Pouncey and defensive end Cameron Heyward were given the night off.
Offensive tackle Alejandro Villanueva returned to practice, along with Burnett and Davis.
HAVIN' SOME FUN: Cornerback Mike Hilton caught a pass on the sideline that had been overthrown by quarterback Joshua Dobbs. Hilton wasn't participating in the rep and wasn't wearing his helmet, but he still sprinted down the sideline toward the end zone.
NOT HAPPY: Wide receiver JuJu Smith-Schuster caught a pass near the goal line but was knocked out of bounds by defensive back Cameron Sutton short of the end zone. Smith-Schuster responded by punting the ball.
EXTRA POINTS: The defense won "Seven Shots" for the seventh consecutive practice, 4-3 … Running back Fitzgerald Toussaint had a 21-yard burst in "Team Run" and might have scored had he not stumbled upon approaching Sensabaugh at the end of the run … Inside linebacker Jon Bostic started every 11-on-11 period next to Vince Williams with the first-team defense for the third consecutive practice. Inside linebacker Tyler Matakevich got a little first-team work next to Bostic in place of Williams … Cornerback Malik Reaves had an interception against Dobbs … Announced attendance was 10,083.
