Free and Parnell each worked with the first team, similar to the arrangement they had toward the end of the 2012 season.
Offensive line coach Bill Callahan said Free's mindset is good, despite the fact that Free accepted a 50 percent pay cut in his base salary and is competing with Parnell.
"He knows that I love him and I want him here and I care about him," Callahan said of Free. "There is no aftereffect that needs to be said because we were working here all along. I think there will be really good competition between both tackles."
Speaking about Parnell, Callahan said, "I see a lot of growth. I see a lot of maturation relative to his understanding of the game. His techniques are improving. I'd like to see him continue that progress and be a more consistent player down in and down out."
There were numerous pairings with the interior of the offensive line Tuesday, but when it came to the first-team tackles, Tyron Smith was the left tackle and Free and Parnell shared time on the right side.
