Kris Humphries to have MRI on shoulder

NEWARK, N.J. -- New Jersey Nets power forward Kris Humphries will undergo an MRI on his left shoulder on Tuesday morning, and coach Avery Johnson doesn't anticipate him being able to travel with the team to Boston for Wednesday night's game against the Celtics.

"Hopefully we'll get some good news," Johnson said. "It's not looking good right now because he barely can move his shoulder, so again we'll have to hope and pray it's nothing serious."

Humphries sat out the Nets' 108-94 loss to the Indiana Pacers on Monday night with a sore left shoulder. Johnson said the 26-year-old woke up feeling hurt.

Humphries has averaged 12.4 points and 10 rebounds in five games for the Nets (1-5), who have now dropped five in a row after winning their season-opener in Washington.

Shelden Williams started in Humphries' place, scoring two points and grabbing six rebounds. Rookie second-round pick Jordan Williams was activated, and made his NBA debut, going scoreless in three minutes. The 21-year-old had been out with dehydration.

"It's been tough," Jordan Williams said. "But it was a dream come true for me (to play in the NBA)."

Point guard Deron Williams went down hard after being fouled by Tyler Hansbrough while attempting to finish a layup at the rim with 5:13 left in the second quarter. The 27-year-old remained on the ground for a while. He was escorted to the bench by trainer Tim Walsh, and appeared to be favoring his right side. But Deron Williams recovered, made both of the ensuing free throws, and then, after a short rest, finished the game.

"I played the rest of the game, I'm fine," said Williams, who finished with a game-high 22 points and eight assists in 34 minutes."

Deron Williams said he doesn't expect to go for any further tests.

"Not that I know of," he said.
