NEWPORT Gwent Dragons are down to the bare bones in the backs for Saturday’s Guinness Pro12 clash with in-form Glasgow at Rodney Parade.

Fly-half Jason Tovey is out for two to three weeks after suffering a calf injury in the 17-15 defeat to the Ospreys last Friday and has been joined on the sidelines by teenage centres Jack Dixon (wrist) and Tyler Morgan (knee).

A late call will be made on full-back and captain Lee Byrne after he suffered a shoulder injury against his former region.

Experienced centre Ashley Smith makes a welcome return from a foot injury but has not played since March and has only just returned to full training while 17-year-old Barney Nightingale is included in the squad.

Wales Under-20s fly-half Angus O’Brien is likely to make his first regional start after impressing as Tovey’s replacement against the Ospreys.

Dragons squad: L Byrne, H Amos, G R Jones, B Nightingale, A Smith, A Brew, M Pewtner, A Hewitt, T Prydie, A O’Brien, D Jones, R Rees, J Evans, L Jones, B Stankovich, O Evans, E Dee, R Thomas, R Buckley, H Gustafson, L Fairbrother, D Way, D Young, I Gough, C Hill, R Landman, M Screech, N Cudd, L Evans, J Thomas, J Benjamin, A Powell, T Faletau.
