Newcastle goalkeeper Tim Krul will miss this weekend’s trip to Southampton with a knee injury. The Dutch stopper, 25, is set to sit out Newcastle’s next three games with the knock he received in Tuesday night’s 0-3 defeat to Everton. Krul will be replaced in the starting line-up by Rob Elliot, who has only just came back from injury himself. The former Charlton goalie has recently been named in the Republic of Ireland’s international squad by Martin O’Neill and will use this opportunity between the sticks at St James’ Park as a chance to further impress his country’s manager. Teenage goalkeeper Jak Alnwick will likely become Elliot’s understudy at St. Mary’s on Saturday. The injury to Krul comes at a time when Newcastle are already without a few big names, with Mathieu Debuchy and Loic Remy still sidelined. Remy is closing in on a return to fitness and will train over the weekend, while Debuchy looks at the game against Manchester United at SJP as a more realistic comeback game. Davide Santon is also nearing a return to the first-team and the Italian is back in full training and could be considered for the Southampton game this Saturday.
