Gold Coast Titans forward Ashley Harrison must pass cognitive test before he can play against Brisbane on Friday night Titans forward Ashley Harrison is expected to return this week after missing a game through concussion. Picture: Adam Head Source: Gold Coast Bulletin TITAN Ashley Harrison is proof of why bans for concussion in rugby league should become mandatory. Queensland Origin forward Harrison (below) wanted to play last Sunday after being knocked out by a Richie Fa'aoso shoulder charge, but was banned by club doctor Paul Ohmsen. Harrison suffered no headaches, no memory loss and no symptoms in the days after he was flattened. "I felt within myself I was fine to play, but obviously he is the one with all the experience in that area and I had to take his advice," Harrison said. I was pretty lucky. I was fine, I didn't have any ill-effects. I was pretty clear in the head, but you know the doc was adamant pretty much on the Sunday that I wasn't going to play just from the severity of the head knock, and the bit of whiplash and then the head hitting the ground as well. I don't like them (the concussion rule), because I missed a game. But they're obviously there for a reason. Harrison must still pass a cognitive test to play Brisbane on Friday night, while centre Brad Takairangi must pass a fitness test on his hamstring. St George Illawarra skipper Ben Creagh would welcome Josh Dugan to the club, but warned the NRL bad boy off social media, with the Dragons shaping as the sacked Canberra star's last-chance saloon. Dugan and his manager met with salary cap auditor Ian Schubert and members of the NRL's welfare department yesterday to establish a potential timetable for his return to the code. Dragons chief executive Peter Doust said on Monday the club was still interested in signing Dugan, pending the result of the meeting with the NRL.
