JULY 31ST: The Celtics have officially re-signed Dooling, according to a team release.
JULY 24TH: The Celtics and Keyon Dooling have agreed to terms on a one-year contract, a source tells Paul Flannery of WEEI.com (Twitter link). ESPN.com's Chris Forsberg confirms with Dooling's agent that the guard will be returning to Boston on a one-year deal (Twitter link).
Because Dooling played for the Celtics last season, he was eligible to sign for more than the veteran's minimum, but Forsberg confirms it'll be a minimum-salary deal (Twitter link). Dooling's 4.0 PPG and 6.9 PER in 2011/12 were both career lows, so a larger guarantee was unlikely, though Forsberg adds that the 32-year-old's "locker room leadership" is invaluable (Twitter link).
Having used their full mid-level exception to sign Jason Terry, the Celtics will be hard-capped at $74.3MM this season. They'll only be on the hook for $854,389 of Dooling's $1,352,181 salary, with the league covering the remaining portion.
