Ireland Under-20s fly-half Tom Wood is set for his senior debut when Munster travel to Glasgow in the United Rugby Championship on Friday night (19:45 GMT).

The 19-year-old, who is the son of former Ireland captain Keith Wood, has been named on the bench with Jack Crowley among the Ireland internationals missing to prepare for the Six Nations and JJ Hanrahan injured.

Hanrahan had been set to start Munster’s win over the Dragons last week but pulled out late, with Tony Butler instead starting at Musgrave Park.

Butler has kept the 10 jersey for the trip to Scotstown and will again form the half-back pairing with Ethan Coughlan.

Munster head coach Clayton McMillan has made four changes to the side that beat Dragons.

Centre Alex Nankivell will miss three to four weeks with a foot injury, meaning Diarmuid Kilgallen comes on to the wing with Shane Daly switching to midfield.

Props Josh Wycherley and Oli Jager take the places of Jeremy Loughman and Michael Alaalatoa respectively, while lock Evan O’Connell replaces South African World Cup winner Jean Kleyn in the second row.

Munster go into the game fifth in the URC, five points behind league leaders Glasgow.
