Mason could be heading back to Plymouth Argyle after leaving Wolverhampton Wanderers.
Mason has been linked with both clubs since leaving Wolves ahead of last month's transfer deadline.
"But I got a phonecall from Steve Gallen [head of recruitment] literally 10 minutes ago saying the owner said no, we can’t bring in another striker because we’ve got Lyle [Taylor], Josh [Parker] and Igor [Vetokele]."
Plymouth-born Mason began his career at Home Park, where he scored 13 goals in 54 games before leaving for Cardiff City in 2011.
Wolves paid £3.5 million to sign him from Cardiff three years ago [Transfermarkt]. However, he only played 39 times for the Molineux side, scoring on seven occasions, and made his last appearance in May 2017.
The former Republic of Ireland Under-21 international spent the first half of the campaign on loan to Plymouth and Charlton's League One rivals, Portsmouth.
Is the former Wolves striker Plymouth-bound now?
