When Newcastle goalkeeper Tim Krul went down injured briefly a fortnight ago, there were calls from some fans for the club to recall loanee Karl Darlow.
If an injury happened in central defence, it's unlikely that the same conversations will be had surrounding Jamaal Lascelles, based on his season so far.
Newcastle bought both players in the summer, loaning them straight back to the Championship side, and while Darlow is the club's first choice goalkeeper, Lascelles has struggled to get a look-in.
The 20-year-old had only made three substitute appearances in the Championship all season for Forest before the weekend, in which he finally got his first start.
It did not end well, with Stuart Pearce's side suffering their heaviest away defeat of the season, losing 3-0 to Huddersfield Town.
Naturally the fact it was his first game of the season in the league, should be taken into account, but it was not an especially auspicious return to the side, with Lascelles failing to win a single tackle at centre-back and making only one interception.
His pass completion rate of just 80 per cent was the lowest of Forest's defenders, and to say he was rusty would be fair.
So should Newcastle fans be worried about Lascelles? A look overall at his season so far suggests clearly that he is not ready for the challenge of Premier League football.
He is unable at present to establish himself at Championship side Forest, and while his purchase was one as 'for the future', early on, it's clear there is work to be done.
The real chance to assess him will begin from now, for he has not had a look in until this point. Lascelles was brought in for Kelvin Wilson, although it's unclear whether he will retain his place.
Perhaps his best chance lies with establishing a partnership with former Chelsea youngster Michael Mancienne, but their first outing together on Saturday did not go according to plan.
Newcastle will no doubt be watching with interest, and of course if they do not see the level of improvement they desire, they could even elect to let him stay at Forest another year.
