Petrov the only worry for Celtic’s crucial clash

CELTIC star Stilian Petrov was still giving manager Martin O’Neill some concern yesterday as the midfielder battled to face Celta Vigo in the UEFA Cup on Thursday night.

The Bulgarian needed 15 stitches inserted after suffering facial injuries after a collision with Livingston’s Marvin Andrews yesterday.

The 22-year-old’s face looked bruised and swollen as he reported to Parkhead for treatment this morning amid fears the injury could become infected.
