Green likely to make Test debut

All-rounder Cameron Green will make his Test debut on Thursday against India at the Adelaide Oval, provided he passes a final concussion test on Wednesday, Australian coach Justin Langer has confirmed.

The 21 year old has made positive steps forward in his recovery from a head knock sustained on the opening day of the tour match against India at the SCG last Friday, Langer confirming the WA young gun will play should he be deemed fit to do so.

"If he's passed fit he'll definitely play," Langer said.

"We are just going through the protocols. He had another test this morning which we got good news on. He's a terrific young bloke, obviously an excellent talent, he's earned the right for selection through his performances. It's very exciting for Australian cricket for him and his family."

Green's inclusion means a potential change at the top of the order, with one of Joe Burns or Marcus Harris set to miss out with Matthew Wade firming to open the batting to allow Green to slot in at number six.

Langer said a decision would be made on the opening combination in the next 24 hours, confirming that number three Marnus Labuschagne won't make the move up to open.

"I have been backing Joe in the whole time," Langer said. "He's a very good player, you don't lose your talent overnight. He also understands that runs are the greatest currency to any player and he's been a bit light on. We'll get eyes on him today, see how he's going, have a chat to him and we'll make our decision on who will open in the next day or so.

"Marnus won't be opening, he's done an amazing job at No. 3. Steve Smith does an amazing job at No. 4. We'll try and stay as settled as possible while David [Warner] is injured. We've got some tough decisions to be made.

Having been hit hard by injury already this summer Australia's plans could be rocked further after star batsman Steve Smith failed to complete training on Tuesday due to a back ailment, with management saying the 31 year old was held back as a precaution.
