Sexton must prove fitness for Cardiff clash

"He will have modified training during the early part of the week with an expectation that he will train fully towards the end of the week."

Johnny Sexton must come through “modified training” to prove his fitness for Ireland’s pivotal RBS 6 Nations clash against Wales in Cardiff.

Ireland’s lynchpin fly-half has “hit all his markers so far” in battling hamstring trouble, but is still fighting to recover to face Wales on Saturday, according to team manager Mick Kearney.
