According to manager Conor Ridge, the Ulsterman caught his right hand in a door at his hotel just prior to leaving for his second round at Mission Hills Golf Club in Shenzhen, China.
'He got it treated this morning. It was obviously quite sore because he said it feels like it's broken,' explained Ridge. 'They've confirmed since that it's not broken, just bruised.'
McDowell played through the pain Friday, but managed only a 3-over 75 and now stands T-56 among the 78-player field, 18 shots behind leader Louis Oosthuizen. According to Ridge, McDowell will decide whether to continue this week after further medical tests on Friday.
In addition to this week's event, the 2010 U.S. Open champion is currently slated to compete in the DP World Tour Championship in Dubai, the Australian Masters and the World Challenge presented by Northwestern Mutual in California before concluding his 2012 season. Despite the odd injury, McDowell's manager remains confident that the show will go on.
'He's not going to want to miss any of them,' Ridge noted. 'He won't want to miss the last two rounds here, let's be honest. Hopefully he's OK, but knowing him he'd have to be pretty bad not to play.'
After the round Friday, McDowell went to Twitter to give an update on the situation.
'Busted up my hand a bit last night...had an argument with a door,' he tweeted. 'Nothing broken. Just bruised and swollen. Should be okay for tomorrow.'
