Queensland Reds reserve flyhalf Tim Walsh has been sidelined for the next four to five weeks with a broken hand, joining Rod Davies on sidelines after a bruising loss to the Blues at Ballymore.
The Reds are also awaiting news on fullback Peter Hynes (dislocated finger) and reserve scrumhalf Richard Kingi (hamstring strain) before deciding on who will fly out for Friday's Round 4 clash with the Chiefs in Hamilton.
Davies (fractured cheekbone) clashed heads with team-mate Daniel Braid at Ballymore on Saturday night in the 27-18 loss to the Blues, while Walsh picked up his injury playing for the Reds 2nd XV on Sunday.
Hynes came off against the Blues at the same time as Davies after battling on despite injuring his hand early in the match, while Kingi picked up his injury on Sunday.
"Peter Hynes we won't know about until tomorrow so we'll just have to wait and see on that, and it's the same story with Richard Kingi," said Reds coach Ewen McKenzie.
"We'll make a call on those two closer to the time, but we are developing depth in our squad and we'll cover it okay if we have to."
"We're lucky to have Ben Lucas (scrumhalf/flyhalf) available to us again after injury (calf), while we have experienced wingers like Brando Va'aulu, Blair Connor and young Wallaby tourist Luke Morahan keen to get an opportunity."
McKenzie said the injury to Walsh was particularly bad luck for the 30-year old, who had fought his way into the Reds from the Wider Training Squad with some impressive pre-season performances.
"Walshy showed his experience and professionalism early in the season and came off the bench for us twice in our first three competition games," McKenzie said.
"So it's particularly bad luck for him to get injured now. Rod Davies is also unlucky, after working so hard to make the squad, but injuries are an unfortunate fact of life in this competition and we have to deal with it."
Walsh, who first played for the Reds in 2004, returned home to Brisbane this year after a lengthy stint overseas and interstate, and impressed with his performances in the pre-season trials. He is awaiting confirmation on whether his injury will require surgery.
