Mo Williams to get MRI on thumb

MIAMI -- Utah Jazz starting point guard Mo Williams plans to schedule an MRI test on Sunday to determine the severity of a right thumb injury he sustained midway through Saturday's loss to the Miami Heat.

Williams was hurt late in the second quarter and did not return for the second half of Utah's 105-89 loss. The Jazz wrap up their four-game road trip Sunday in Orlando, but coach Tyrone Corbin was uncertain of Williams' status.

An X-ray taken on Williams in Miami was negative, but the 10-year veteran said the pain in his thumb was similar to what he felt when he tore a ligament in his hand in 2008.

"I can't feel it now," Williams said after the game of the numbness. "It's the same feeling (as in 2008). I'm just crossing my fingers that the MRI is negative."

The Jazz immediately felt the impact of the absence of Williams, who averages 13.3 points and a team-best 6.8 assists per game this season. Utah, which trailed 47-43 at the half against Miami, was outscored 58-46 in the second half and also surrendered 20 points on 11 turnovers over the third and fourth quarters on Saturday.

"It hurt us," Corbin said of missing Williams in the second half. "It took our pace and speed down. He's one of our key guys, and we need all our pieces, especially against a team like the Heat on the road."

Williams had five points, four assists and three turnovers in just more than 16 minutes Saturday before he was hurt. With Williams in the locker room, veterans Earl Watson and Jamaal Tinsley shared the point guard duties in the second half for the Jazz, who have lost four of their past five games to fall to 14-14 on the season.
