Did one of them withdraw from the tournament?
OK, I found it:
Defending champion Mikhail Youzhny pulled out of the tournament on Wednesday due to a virus. Mathieu replaced him in the main draw as a lucky loser and is now set for a first career meeting with Istomin. The 108th-ranked Frenchman has been rounding into form of late following physical problems to start the year, but he lost to Victor Crivoi in qualifying. Istomin, enjoying his best year on tour, beat Illya Marchenko in his opener on Tuesday. This should be a close three-setter, with a slight edge going to the 46th-ranked Uzbek.
