Rory McIlroy, playing with a bandaged forearm, struggled to two over par at the turn in the second round of the PGA Championship on Friday.
The US Open champion hurt his wrist on the third hole on Thursday and played through pain to finish even-par, leaving his participation in the tournament in doubt.
The Northern Irishman underwent an MRI scan on Thursday which showed he had strained a tendon in his right wrist.
McIlroy walked on to the practice range just 25 minutes before his tee time with tight strapping around his wrist and lower arm and a bandage up the length of his forearm.
The 22-year-old’s appeal was evident from the six television cameras that followed his every move as he teed off on the 10th tee. He drove sweetly down the centre of the fairway as he began his attempt to catch up wioth first round leader Steve Stricker, who has a two-shot advantage over fellow American Jerry Kelly after shooting 63 on Thursday.
There was an early setback to that bid, though, as McIlroy bogeyed his opening hole as he three-putted but a birdie on the 12th was followed by another on the 16th where he sank a 45 foot putt to the delight of his fans.
Europe's main challenge to Stricker came from Dane Anders Hansen who was two under par through 14 holes to move within a shot of Kelly.
DA Points had the best front nine of the day with a 32, putting him level with Hansen at three strokes off the lead. American Brandt Snedeker was handed a two-stroke penalty for being lateAmericans.
JB Holmes (illness) and Rocco Mediate (injury) withdrew from the tournament along with injured South African Retief Goosen.
Bad start for Atwal
Arjun Atwal made yet another horrendous start to his Major golf championship campaign with an eight-over 78 in the opening round of the PGA Championships. He is now 138th and way off a cut-line that looks likely at around three-over at the 7,467-yard course.
Atwal was fine through the front nine with a bogey and a birdie for an even-par turn. Then came the disaster in the form of a triple bogey on 11th, 12th and then two more doubles on par-three 15th and 17th for an eight-over 43 on the back nine and a card of 78.
