Lynn boss Gary Setchell admitted Jack Defty's knee injury was a hammer blow ahead of key league and cup battles this week.

Town's prolific striker will miss Wednesday's league trip to Blackstones and the FA Vase test at Gresley after damaging medial ligaments during the club's seventh consecutive UCL Premier Division away win of the season.

Danny Beaumont's eighth minute strike secured the points but Defty's injury exit was the main talking point after he landed awkwardly following an aerial duel with Daventry keeper Anthony O'Connor barely five minutes into his second half cameo.

'We thought initially we were maybe talking four to six weeks out,' said Setchell. 'After getting some tests done we feel it might be a bit sooner. Let's hope for a cold snap. It's terrible timing with games coming up Wednesday and then Saturday. We actually looked to rest him today and I only put him on in the last 15 minutes to deal any threat from set pieces.

'He has gone up for a header and looks like he has landed at an awkward angle on his knee. It's nothing short of a disaster that he is not fit for the FA Vase. After watching them play the other day as well I know they are a big strong side with some big players so that is bad news for us. He knew straight away and signalled to come off. Anyone who knows Jack will know he is not one to come off because he regularly plays with all sorts of injuries. We have to re-group, assess Jack and then go from there.'

Setchell acknowledged Town never scaled the heights of recent displays despite Beaumont coolly slotting Robbie Harris' cushioned pass for the perfect early start.

'Since Tamworth we had been playing so well and when it didn't work we panicked as a group,' he said. 'We started knocking it long to small forwards, we weren't making angles for the passes - it was a sub standard performance. I thought the back four played reasonably well and we managed to get the win. That is what you have to do to win a league and we didn't do it last season. We have had three 1-0 wins away from home now, but after scoring so early perhaps you would have expected something more from us.'

Lynn improved after the interval but were unable to breach a stubborn Daventry backline.

'We had to come up with a plan B which meant playing in there half,' said Setchell. 'We tried to make the pitch big but because we hadn't retained possession that wasn't working. It wasn't sticking so I just wanted two banks of four, for us to play tight and make them earn a chance. I don't think they made one second half so we have to be grateful for the clean sheet. It's another three points. We have a good side. I thought Ross Watson showed what he was about and Robbie was decent. We just have to believe in ourselves a bit more.'
