Chris Davies has confirmed Alex Cochrane picked up an injury in Birmingham City ’s 2-1 win at Blackburn. Blues trailed 1-0 after Todd Cantwell put Rovers in front early in the second half. But a Jay Stansfield penalty as the game ticked past the 90 levelled the scores, then Lyndon Dykes pounced for a winner eight minutes into added time. Ethan Laird won the spot kick, with a surging run into the box, having replaced Cochrane at left back at half time. Blues were already looking recruit a challenger for Cochrane as the transfer window enters its final fortnight. “He's got a slight knock,” Davies said. “He's just felt something there which is unusual because Alex has been an ever present. “But he's played a lot of football, so we'll have to see how he is tomorrow. “We are looking in that position. We do need two left backs so definitely cover and competition for Alex. “That won't change it too much just by nature we've only got two weeks to go, so it's something we've been looking at doing. “Nothing's imminent in the next day or so from my understanding, but there's definite work to do, no doubt we need the depth. “We need a few more players just to give us what we need depth wise and quality wise for the season ahead. “It's a long old road we've got ahead of us and we're working hard on that, we communicate a lot, myself and the owner and Craig (Gardner), and we're always talking about what exactly we need and working hard behind the scenes. “It just depends how it all falls, but there's not like loads that we need to bring in, but we need a few more just to finish off the squad.”
