Parker says the MRI is "just to make sure" he's improving on schedule from the injury, which limited his effectiveness in the final two games of the Spurs' second-round series against Golden State.
Parker had 15 points and a career-best 18 assists in San Antonio's Game 2 win against Memphis on Tuesday night. The Spurs lead the series 2-0. Game 3 is Saturday night in Memphis.
Parker says his calf feels better and the three-day break between games arrives "at a perfect time for me."
