LAS VEGAS — John Wall arrived in Las Vegas Tuesday for a two-week stay that will include watching the Washington Wizards’ summer league team and his AAU club from his hometown of Raleigh, N.C. participate in a tournament.

By Tuesday afternoon he was in a gym at Thomas and Mack Center working out one week after resuming basketball activities for the first time since the Wizards’ season concluded in the Eastern Conference semifinals May 15. Wall said that his left hand and wrist, fractured in five places in Game 1 of the series against the Atlanta Hawks, has healed.

“It’s fine now. It’s perfect,” Wall said. “I’m back working out so I’m good.”

Wall, who didn’t need surgery, played Game 1’s entire second half with the fractures and returned to play in Games 5 and 6 against the Hawks after a three-game absence. Wall averaged 17.5 points on 37.8 percent shooting along with 10 assists and five rebounds in the two contests.

OUBRE SIGNS CONTRACT

Kelly Oubre Jr. officially signed his contract with the Wizards, according to a person with knowledge of the situation. Oubre, the 15th pick in last month’s NBA draft, inked the deal before the Wizards traveled to Nevada for summer league.
