IRVING, Texas --With Tyron Smith's hyperextended knee a question mark for Sunday, newly-signed guard Derrick Dockery took some reps at tackle on Thursday.
It's a position the ninth-year veteran has played before -- at the University of Texas, almost a decade ago.
The Longhorns moved Dockery to right tackle as an injury replacement for a handful of conference games. He played well back then, but has since played inside throughout his NFL career.
"It's been a while," he said. "It was a little awkward (this week) at first. But now I'm just working on my sets, knowing when to kick, how deep to kick, being able to see your target and move your feet.
"Hopefully our guys can stay healthy and if need be I'll be ready."
