Practice notes: Wells returned

The musical chairs continued on the offensive line today.Center Scott Wells returned to practice today after missing yesterday's workout because of a concussion.However, rookie Evan Dietrich-Smith, who practiced at center yesterday and would be the starter if Wells couldn't play on Sunday against the 49ers, did not appear to be practicing in the portion that was open the media. It was not known what kept Dietrich-Smith out.Tackle Allen Barbre, who sprained his ankle in practice yesterday, was not on the practice field. He's not expected to start anyway. Mark Tauscher took all the work at right tackle.Coach Mike McCarthy has shortened practice today. It's expected to end before noon. We'll have a full injury update then.-- Rob Demovsky, rdemovsk@greenbaypressgazette.comhttp://twitter.com/RobDemovsky
