The Wallabies are sweating on the fitness of Sean McMahon as coach Michael Cheika faces yet another back-row configuration for next weekends Test against Argentina.McMahon has been sent for scans on his ankle after injuring himself in a tackle in the first half of Saturdays 18-10 Rugby Championship defeat to South Africa (Sunday morning AEST).He tried to play on after having it strapped but struggled to run and was swapped at the break for Scott Fardy.The 22-year-old was brought into the team as a replacement for David Pocock (broken hand) and was set for an extended run at No.8, a position he is keen to make his own.Cheika said it was likely a pretty significant injury.Thats two now in that spot, Cheika said. Well see where we end up next week.He was going well when he was on there, that was very positive.McMahons injury could mean a starting debut for Lopeti Timani, the only other recognised No.8 in the current Australian squad, against Los Pumas at Twickenham.Timani was the last man trimmed from the Wallaby bench at Loftus Versfeld, having made his first international appearance as a reserve in their previous Rugby Championship clash in Perth.Alternatively, Cheika could fly over Ben McCalman, who has recovered from a shoulder issue and is playing back home in the National Rugby Championship.Vice-captain Michael Hooper is still hopeful McMahon wont miss a game, describing him as a player they need in the team.He seemed pretty positive, Hooper said. Hes a hard, hard bloke, so its going to take a lot for him to not play.Were hoping for the best there because the involvements he had early on in the game were fantastic - a couple good carries, turnovers, tackles.We need him in the squad and hopefully thats the result we get.Tom Rathman Super Bowl Jersey .

He said hes hoping Pettway will be able to return for the regular season finale against No. 1 Alabama.Malzahn is taking a wait-and-see approach before determining Whites status against Alabama A&M.White played in the 13-7 loss to Georgia and the second half against Vanderbilt despite an injury to his right, throwing shoulder and struggled badly against the Bulldogs. He said Sunday night that he aggravated the injury during the Georgia game.Itll be a kind of day to day, week to week deal, Malzahn said. Not ready to make a call one way or the other with him. Well play him when hes healthy.White sat out the first half against Vanderbilt because of the injury before coming in and leading the Tigers to the win. He came into the Georgia game as the SECs top-rated passer. Auburn trailed 13-10 at the half against Vandy without him.Against Georgia, White was 6-of-20 passing for 27 yards and had an interception returned for a touchdown while the offense produced just 164 total yards. Those numbers include a handful of dropped passes, too, but his first nine attempts after halftime were either intercepted or incomplete.ddddddddddddWhites only completions in the second half were two 4-yarders on the final drive. Backup John Franklin III didnt play in the half.Malzahn said Auburn coaches talked to White at halftime and he could tell by that look in his eye that the quarterback wanted to play.I would have liked to have known if he was worse, Malzahn said. It would have been good to know. Moving forward, hell communicate better. Hes a tough guy and hes trying to win the game. Its a one-score game, and he felt like he could do it or hed have said something.Those are just the two biggest of a litany of injuries to offensive players.No. 2 rusher Kerryon Johnson has been nursing an ankle injury, but still gained 99 yards and scored the only offensive touchdown against Georgia. Freshman Malik Miller has missed the last five games with a knee injury, but Malzahn said he is practicing this week.Safety Johnathan Ford is working at running back, where he started his college career.Running back Stanton Truitt hurt an ankle early in the Georgia game and will also miss the Alabama A&M game.
