Geelong will monitor stars for concussion Allen Christensen copped another head knock. GEELONG coach Chris Scott has hosed down concerns about the long-term health of young gun Allen Christensen after he suffered another head knock in the 59-point win over Greater Western Sydney. Scott described his side's lethargic performance as far from good enough for a top-four side as the Cats turned an 18-point quarter-time deficit into a comfortable win at Skoda Stadium. Christensen has been prone to concussion in recent seasons, with the sickening collision with teammate Steve Johnson ending his day at the eight-minute mark of the final term. Christensen and Johnson both lay motionless on the turf after clashing heads while trying to collect the ball on the half-forward line. Christensen was first to get to his feet and trotted to the bench while Johnson was helped by trainers and later came from the field. Both donned jackets and played no further part in the clash after Geelong substituted big man Nathan Vardy late in the third term, leaving the Cats with only one rotation. Johnson had 24 touches until the collision and Christensen had 23 in performances that staked claims for best afield honours. Scott said post-match both players were feeling the effects. It was late in the game, so our medical staff were obviously concerned and made the call really quickly on Johnson, so it's something were going to have to monitor closely and Christensen, they were a little more open to him possibly being able to return but eventually decided he wasn't good enough either, so it's too early to tell. Scott said he was not concerned by the latest head knock on Christensen, who copped a hit to the head against Hawthorn in Round 1 and also missed 15 minutes of the clash against Collingwood with blurred vision. Christensen also had concussion issues in 2011 and last year. "Yeah, but only a few (concussions)," Scott said. There are players that have had more than him. We, collectively, get concerned about all our injured players but we are really proud about the strong record we have in regard to being conservative with injury management. Fortunately we've got next week off, but if there are any signs that our players are not quite right to not only take the field but be at their best, we won't play them. Scott admitted he was concerned by his team's lacklustre start to matches, conceding five goals in the first term. Yeah, a little bit. Asides (from) the Port Adelaide game, there's a bit of a pattern there and things we can remedy quite quickly," Scott said. We are concerned and that's obvious. If you watch us closely - even though we're 10-1 at the halfway mark of the season - we really haven't played our best footy, especially early in games. That's something we're going to have to fix because if we did that against this team in three years' time, we won't be coming back. Winning's the most important thing and we've got to keep banking the wins, but the way we play is really important as well. I thought when the heat was on and both teams were fresh, they looked better than us, which is a concern. But we're pretty respectful of the opposition. We didn't come here expecting to win by 100 points. There were things we talked about they certainly delivered on," he said. Scott said it was pleasing to enter the bye 10-1, but admitted there was plenty of room for improvement. I'd even be happier if we had've dropped some extra games but were playing better footy. We are living in the real world, I'd hope, because the type of footy we're playing at the moment is not top-four standard," he said. I'm really confident we can fix that and turn it around quickly, but it's not a given. Scott laid down the law at quarter time after his side trailed by 18 points. "It (quarter-time spray) was similar to the other breaks," he said. We thought they were really good around the ball and it's something we've been really good at in the past, we're just not good at it right at the moment, especially early in games when the opposition's fresh. They pressured us when we had the ball and they got a lot of numbers around the contest, and we didn't handle that situation well. So, we were all a bit frustrated, players and coaches alike because we have been talking and practising those things, we just haven't been implementing when the heat was on. The Giants trailed by seven points at halftime, with Jeremy Cameron bagging two of his four goals. At the other end of the ground, James Podsiadly put on a clinic, bagging four of his five goals for the match but the Cats led by just 12 at the main break. Like the previous week against Gold Coast, the Cats put on the after-burners in the final term and kicked eight goals to one to take the gloss off a gritty Giants performance.
