Sean O'Hair withdraws with neck injury

FORT WORTH, Texas -- Sean O'Hair, who finished tied for 16th at the Crowne Plaza Invitational at Colonial in 2011, withdrew from the tournament Thursday morning with a neck injury.

Sung Kang replaced him. Kang was one of the few alternates still in Fort Worth when O'Hair withdrew, allowing him to get in despite being ninth on the list.

Stewart Cink withdrew Wednesday night and Gary Christian took his place.

Kang is playing with Ben Crane and Jim Furyk this morning.
