Notts County loanee Cristian Montano has returned to West Ham following the expiry of his one-month deal.
The attacker returned to Meadow Lane for a second spell in February after an impressive three months with Keith Curle's side at the start of the campaign.
Curle believes it is time for Tano to move on in search of regular first-team football as high-flying County continue to push for promotion from League One.
"I had a conversation with Cristian and I spoke to his agent as well, and explained that he wouldn't be getting as much football time and field time that a young man with his ability would acquire at this stage of the season," Curle told the club's official website.
"He's got an opportunity to go back to his parent club and he might able to get another move where he can play games.
"I didn't think at the minute I'd be able to offer him enough time and I didn't want him to be sitting back kicking his heels, when there's potentially 10 games he could get under his belt for his career."
