The bad news has been confirmed -- Tyrese Haliburton did, in fact, tear his right Achilles tendon during Game 7 of the NBA Finals on Sunday.
The official diagnosis came on Monday ... just a day after the Indiana Pacers star suffered the leg injury during the first quarter of the season finale against the Oklahoma City Thunder.
Haliburton -- averaging 17.2 points in the playoffs -- was carried off the court ... and was seen using crutches and a wheelchair following the championship loss.
