LaPorta pulled from game after collision

ARLINGTON -- Matt LaPorta felt nauseous after Rangers shortstop Elvis Andrus' elbow clipped him in the back of the head and gave him a contusion Monday night.

If the injury is serious enough to keep LaPorta out of the lineup for a prolonged period, manager Manny Acta, whose Indians team has already been besieged by injury, will probably be feeling a bit nauseous, too.

For now, though, LaPorta's head contusion does not appear serious. The Indians pulled LaPorta from Monday's game after the third-inning collision and sent him to nearby Medical Center of Arlington for a CT scan, which came back negative. LaPorta will be evaluated again when he arrives at the ballpark Tuesday.

Acta stressed that the CT scan was merely a precautionary measure.

"[The collision] pretty much knocked him out," Acta said. "He was out for a little bit. That's why the doctor wanted to have a CT scan done."

LaPorta remained in the game immediately after the collision and finished the inning. But he began to show some concussive symptoms afterward.

"He actually was feeling nauseous, and he threw up a little bit," Acta said. "It was a no-brainer to take him out of the game."

In the aftermath of the Indians' 9-3 win over the Rangers, it was too soon to tell if the injury will keep LaPorta out for a prolonged period.

LaPorta fell hard to the ground and was motionless for several seconds after Andrus' elbow struck him in the back of the head as Andrus crossed first.

Andrus reached on an infield single to short. Shortstop Jason Donald made a diving stop of the ball, then fired to LaPorta at first. His throw skipped in the ground in front of LaPorta and bounced away, allowing Julio Borbon to score all the way from first and Andrus to trot into second.

"It was a short throw," Andrus said. "He picked the ball up, but when he fell back, I hit him in the head. He hit me in my ribs. I'm good. I didn't feel it at all. I was a little surprised because I didn't know where it hit him. I didn't see a replay of it."

The Indians' athletic training staff tended to LaPorta, who appeared momentarily dazed. After getting back on his feet, LaPorta did a few quick jogs in the infield and was deemed fit to return to play. But the following inning, Andy Marte replaced him at first.

It was an eventful inning for LaPorta. In the top of the third, he belted a two-run homer off Rangers right-hander Omar Beltre. It was LaPorta's fifth homer of the season and his fourth since his June 27 promotion from Triple-A Columbus.

LaPorta took over the regular duties at first base after Russell Branyan was traded and is batting .385 (10-for-26) with the four homers and nine RBIs since his promotion.

This is not the first time LaPorta has dealt with such an injury. Shortly after the Indians acquired him in the July 2008 trade that sent CC Sabathia to the Brewers, LaPorta represented the U.S. in the Beijing Olympic Games and was hit in the head by a pitch in a game against China. He missed three games as a result of the blow.
