Tatum — who suffered a ruptured Achilles’ tendon during the Eastern Conference Semifinals in May — was walking gingerly around the field without a walking boot.

The Celtics star made an appearance at the New England Patriots’ joint training camp practice with the Washington Commanders. Tatum, who had surgery in May to repair the ruptured right Achilles tendon injury he suffered in Boston’s Eastern Conference semifinal loss to the New York Knicks, was seen walking without a boot or brace.

Tatum suffered a torn right Achilles tendon on May 12 in Game 4 of the Eastern Conference semifinals vs. the New York Knicks, and quickly underwent surgery to repair the tear. That began what's expected to be a lengthy recovery process, though no official timetable has been communicated by the Celtics.
