Class Brighton defender Matthew Weaire misses Gosport Borough’s key home clash with Hendon on Saturday at Privett Park (3pm).
The 17-year-old loan star went off with concussion during the 2-1 Southern League premier division south defeat against Taunton last weekend.
His absence is a real blow for Borough. He has a made very positive impact since joining from the Seagulls.
Injuries to defenders have hit Gosport hard this season.
Pompey’s Matt Casey fractured his collarbone on his debut earlier in the season after arriving on loan.
Now boss Craig McAllister expects to be without Weaire for a couple of matches.
He said: ‘It’s the curse of the number five shirt again.
‘He’s back at Brighton and they say he will miss at least two games.’
McAllister is desperate for Gosport Borough to halt their slide down the league against fourth-placed Hendon.
Borough’s problems increased with a 2-1 defeat at Farnborough in midweek, leaving them with just one win in over two months.
The 10-man visitors looked on course to pick up a point but an 88th-minute goal condemned them to another defeat.
McAllister’s side are uncomfortably placed just three points above the drop zone having played a game more than 20th-placed Dorchester Town.
Borough also received another body blow when new signing George Bennett, from Basingstoke Town, was sent off on his debut at Farnborough.
McAllister has been chasing a midfield signing for several weeks.
The club, however, are now waiting to hear from the Football Association when his suspension starts.
Borough’s boss believes Bennett can be a good acquisition when he gets him playing again.
He said: ‘He's a good size at 6ft 2in, left-footed and brings balance to the team.
‘Everyone talks about wanting left-footed players but there aren't that many around.
‘He can play a holding role and an attacking role.
‘The lad offers different attributes to what we already have and yes he's young, but he has played more than 100 games at this level so he knows the situation.
‘Coming here is a challenge for him because we want the club to progress and we see him being part of that and helping us get to where we want to be.
An ankle problem for Joe Lea and a foot injury to Tony Lee are also concerns ahead of the match.
