Right guard Chris Chester returned to practice and is expected to play Saturday vs. Indianapolis. Chester missed the first two preseason games because of a sprained left ankle.

…Running back Roy Helu said it’s too early to know if he’ll be ready to play Saturday. But he hasn’t practiced in more than a week because of sore Achilles’ in both feet. He said his left Achilles was tight and then became painful while the right one is just tight.

When he runs, Helu said, “it’s like your body wants to run but the Achilles just won’t happen.”

…Running back Tim Hightower missed practice to attend his grandfather’s funeral.

…Fullback Darrel Young, who held out hope earlier in the day that he would play Saturday, is unlikely to face the Colts. Coach Mike Shanahan said Young, sidelined with a left hamstring injury, is in the 85-90 percentile.

There’s a chance Young will play in the preseason finale, even if the rest of the starters aren’t.
