Kevin Doyle posts gruesome picture of gashed leg on Twitter

Robbie Keane is also out of Tuesday night's friendly against Slovakia.

Republic of Ireland skipper Robbie Keane is out of Tuesday night's friendly against Slovakia as he grows increasingly concerned over a niggling knee injury.

However Keane was not the only Ireland striker seeking medical attention on Friday evening, with Colorado Rapids frontman Kevin Doyle preparing to have a horrific gash on his shin stitched up after an ugly clash with Norwich defender Timm Klose which saw him leave the pitch on a stretcher.
