Brown out for eight weeks but Sunderland defender will return for run-in Sunderland defender Wes Brown is likely to be sidelined for eight weeks by his knee injury. The former Manchester United man damaged a knee during Sunday's 1-1 FA Cup fourth round draw with Middlesbrough, and it was at first feared that his season could be over. However, a scan has revealed that the damage may not be as extensive as was first thought. Fears: Sunderland were worried Wes Brown would miss the rest of the season Manager Martin O'Neill said: 'We don't think he needs the operation, but he will be two weeks in a brace, two weeks elsewhere and you are looking at probably about eight weeks before he is back. 'But at one stage, it looked like a season-ending injury.' Midfielder David Vaughan too, could be missing for several weeks after damaging ankle ligaments during the same game. Party time: Stephane Sessegnon celebrates scoring against Norwich O'Neill said: 'David was feeling better today, but he is still very, very sore and the swelling is still up, and we are looking at a few weeks for him.' However, the news is better of midfielder Lee Cattermole, who missed the reunion with his former club after suffering a hamstring strain in training. O'Neill said: 'Lee is feeling a lot better and he is hoping to start running at the back end of next week.' good job MARTIN brought in some cover Martin O'Neill says he's pleased with his transfer business after bagging two defenders on deadline day. Manchester City left-back Wayne Bridge arrived on loan, with a similar arrangement struck to bring in Sotirios Kyrgiakos from German side Wolfsburg. O'Neill identified a need for defensive cover due to injuries and moved quickly and decisively to boost his squad ahead of the remainder of the season. Bridge made his debut as a substitute during last night's 3-0 win over Norwich while Kyrgiakos, who didn't sign in time to be included, could make his debut against Stoke this weekend. "We needed to bring Wayne in," he said. "We had one loan left from this country and we did that and then we brought in Sotirios Kyrgiakos. "We've got a lot of centre-backs who are injured at the moment. "Despite the news on Wes Brown being a little better than we first feared, he's still going to be out for a bit of time, so from that viewpoint we wanted to get some players in and we did just that. "I'm delighted to get a little bit of help for this team - they deserve that help. The boys are doing very well at the moment; I'm delighted with how things are going."
