Southend boss Paul Sturrock is yet to reach a decision over a possible loan move for Rowan Vine.
The QPR striker bagged a late winner in a trial game on Tuesday afternoon to give the Shrimpers' reserves a 1-0 win over Oxford, although Sturrock was left with concerns over the fitness of Vine, who has not played first-team football since September.
"With our injuries and everything else it's been very difficult for me to really consider what's best," Sturrock said. "He didn't look fit to me and that's a worrying aspect - how long it would take. That's something I've been talking to the fitness coaches about."
Sturrock is also deliberating over a move for centre-back Christian Dailly, 38, who also started the reserve-team clash.
Meanwhile, a long-awaited decision over the future of Southend winger Bilel Mohsni is expected to be announced by the npower League Two club soon.
The mercurial winger has not played since the 1-0 defeat at Morecambe in late February when, not for the first time this season, his behaviour attracted the headlines for all the wrong reasons.
