Shawn Marion has hyperextended knee

DALLAS -- Dallas Mavericks forward Shawn Marion said he hopes his hyperextended right knee doesn't worsen overnight after Oklahoma City Thunder center Kendrick Perkins fell on him during a scramble for a loose ball with four minutes to play in the second quarter Wednesday night.

Marion, however, managed to stay in the Mavs' wild, and at times strange, 95-86 loss to the Thunder.

"Oh yeah," Marion said when asked if he considered coming out. "I kept it warm with heat packs every time I went out. We were shorthanded enough."

The Mavs were already playing without starting point guard Jason Kidd (strained right calf), and then starting center Brendan Haywood, who complained of lower back stiffness, and reserve forward Lamar Odom (stomach ailment) were surprise scratches.

Marion, whom coach Rick Carlisle has called the Mavs' best player through one-third of the season, chased a loose ball headed toward the baseline. The 6-foot-10, 267-pound Perkins, who made a steal on Vince Carter and pursued the ball, fell on Marion's leg and his big body pushed into Marion's knee.

Marion stayed on the floor momentarily and got up with the help of teammates and was clearly in pain as he tried to flex his knee.

"It hurt," Marion said. "It's still sore right now."

Dallas called a 20-second timeout and Marion returned to the floor and played the remainder of the half, scoring on a reverse tip-in off a Dirk Nowitzki airball with 0.6 seconds showing on the clock to give the Mavs a 52-49 halftime lead.

Marion played 17 minutes in the second half, including 10 in the fourth quarter. He was just 2-of-7 from the field for four of his 12 points. He also had a team-high 10 rebounds, including six on the offensive glass.

The Mavs are scheduled to practice Thursday morning and will play the Indiana Pacers at home Friday night.
