VINCE Grella is a major injury doubt ahead of Rovers’ trip to Aston Villa tonight after his impressive home debut on Saturday.

The Australian midfielder played his first full 90 minutes since signing from Torino in the summer but is now struggling with a slight hamstring strain.

If Grella misses the clash, veteran Turk Tugay is expected to step in to partner Stephen Warnock for the visit to Martin O’Neill’s in-form Villa.
