INDIANAPOLIS -- James Hinchcliffes tough IndyCar start is getting more clouded. E.J. Viso replaced the injured Canadian on Sunday in the opening practice for the Indianapolis 500 and its still unclear when the popular Hinchcliffe will turn his first laps on the famed 2.5-mile oval. Hinchcliffe, from Oakville, Ont., was injured Saturday in the inaugural Grand Prix of Indianapolis when debris from Justin Wilsons car flew into the cockpit, striking Hinchcliffe in the head. He was taken away from the track on a stretcher, transported to a hospital and diagnosed with a concussion. He was hoping to be re-examined Sunday, but that never happened and now hes out until at least Tuesday. "Well have a better feeling then," team owner Michael Andretti said. "They just said rest and they dont want to see him again until Tuesday." Later, the team issued a statement saying that exam date has been scheduled. Traditionally, IndyCar drivers with concussions have missed a minimum of seven days off before being cleared to race. But series officials issued a statement Sunday night, saying concussions are handled on a case-by-case basis and that drivers with head injuries must pass an ImPACT test before theyre cleared to compete by series medical director Dr. Michael Olinger. If Olinger adheres to the strict timeline, though, Hinchcliffe would miss the only full week of Indy practice and might not be back in the No. 27 Honda until next weekend when the only two qualifying sessions will be held. Andretti brought in Viso, who hadnt even been in an IndyCar this season until completing 28 laps Sunday. Even Viso isnt sure what to expect next. He finished sixth on the speed charts with a fast lap of 222.105 mph. Twenty-four cars made it onto the track. Australias Will Power, who drives for Roger Penske, was the fastest of the 24 cars at 223.057 mph. Viso said he is prepared to do whatever Andrettis team needs -- even if that means replacing Hinchcliffe for qualifying or in the May 25 race. "Its too early to know. It just happened yesterday and nobody knows how hes going to recover. It 100 per cent comes down to his recovery," the Venezuelan said. "First of all, I just wish James a quick recovery. If he takes a little bit longer and Im able to drive and do the job for him Im, of course, not disappointed with that. But for me, the most important thing is to understand that hes recovering fast." He has made six straight starts in the 500, including a career best fourth last year. Viso finished 18th in 2013, matching his best career finish at Indy. The team said Hinchcliffe did make a brief appearance at the track to meet with his crew and have lunch with his family. He also spoke briefly with Viso but did not take questions from reporters. For the popular Canadian driver, its already been a challenging season. He started second at Long Beach and Barber but has not finished higher than seventh in any of this seasons four races. He qualified 11th for Saturdays race, then wound up 20th after leaving with the head injury. In Hinchcliffes three previous IndyCar seasons, hes had 14 top-five finishes in 50 starts and won three races -- with all three coming last season. What everyone wants to know now is whether hell get a chance at a third straight top-nine qualifying run at Indianapolis? "He seems in good shape and hes going to recover fast," Viso said. Andretti Autosport has five cars, including NASCARs Kurt Busch, trying to qualify for the May 25 race. Ryan Hunter-Reay had the fastest car of the bunch, turning a lap of 222.134 on Sunday. Busch, who is trying to become the fourth driver to race 1,100 miles in one day, at Indianapolis and Charlotte, was 12th at 220.352.

People familiar with the case told The Associated Press on Friday that arbitrator Fredric Horowitz could issue his decision this weekend.MEMPHIS, Tenn. -- With Tony Allen back, the Memphis Grizzlies were able to turn up their defence pressure and hold off the Los Angeles Clippers down the stretch. Zach Randolph had 21 points and 11 rebounds, Marc Gasol added 17 points and 10 rebounds, and the Grizzlies survived a late rally for a 102-96 victory over the Clippers on Friday night. Allen, the Grizzlies defensive sparkplug, missed the previous 21 games with a sprained left wrist. His return sparked a defensive effort that held the Clippers to 33 per cent shooting in the second half and gave Memphis a double-digit lead that was enough of a buffer for the Grizzlies to win their fourth straight. Allen scored nine points on 4-of-4 shooting with two steals and a block. "With TA back in the lineup, its great," Randolph said. "Hes a leader on this team, and he gets guys going with his energy. What else can I say? Were happy to have him back." Allen drew a standing ovation when he entered the game late in the first quarter and seemed even more animated than usual in seeing his first action since Jan. 3. He said his goal was "to get in there and cause havoc." "I kind of had butterflies in my stomach when they did that," Allen said of the ovation, "but I got focused on the game." James Johnson added 15 for Memphis, and Mike Miller finished with 13, hitting 5 of 8 from the field. Courtney Lee scored 10 for Memphis. Gasol had four blocks. Blake Griffin led the Clippers with 28 points and 13 rebounds, and Jamal Crawford had 23 points. Chris Paul added 18 points and 14 assists, but was 4 of 13 from the field as Los Angeles lost its second straight. "It was just one of those games that we missed a lot of easy ones," Griffin said after Los Angeles shot 39 per cent for the game. Clippers coach Doc Rivers thought the game started slipping away in the second quarter. Riveers, who coached Allen in Boston, noted that he was a key.dddddddddddd "I thought Tony Allen, Mike Miller and James Johnson turned the game around for them with their energy," Rivers said. Another key was the bench scoring. Memphis reserves outscored their Clippers counterparts 43-7. "When we dont score, thats fine," Rivers said, "but weve got to be able to get stops. Our second unit didnt kill this offence, they gave up 32 points defensively, and that thats what hurt us." The Grizzlies opened the fourth quarter connecting on their first four shots for an 11-4 run to take the lead to double digits. Mike Conleys layup gave Memphis an 84-72 lead with 9:23 remaining. The margin stayed between seven and 11 points, and Memphis still led by 10 approaching the 4-minute mark. But Los Angeles chipped away, and a pair of free throws from Paul brought the Clippers within 98-96 with 1:05 left. That was as close as Los Angeles could get. Memphis scored the last four points while the Clippers were missing their final four shots. As has become the norm when the two teams face each other, the play was physical and defence stout. "Every game we play against them is going to be a battle, and we understand that," Conley said. "Both teams get up for each other, and (Los Angeles) is the most competitive team, I think, as far as rivalries go." NOTES: Griffin has scored at least 25 points in 10 straight games. ...
