Morgan Whittaker is in talks with multiple League One clubs over a potential loan exit from Swansea City.
The attacker was not involved in the Swans' pre-season win over Plymouth Argyle on Tuesday night but was in attendance at Home Park. And the 21-year-old appears destined for another loan spell away from the Swansea.com Stadium having spent the latter half of last term at Lincoln City.
"Morgan wasn't involved tonight because he's discussing a loan move as it stands," said Martin. "It might not be the right one for us or for him, so we'll see where that comes to."

The Swans have already added Matty Sorinola, Joe Allen, Nathan Wood and Harry Darling to their ranks this summer but are eager to offload other fringe players in a bid to free-up funds and squad places to bring in additional recruits.
It's understood the Swans want at least a right wing-back and a central midfielder while further signings may well be required depending on the number of exits.
"I think we need a few players in a couple of different areas," added Martin. "What areas we need them in I think will become more evident as the games go on and we'll have a bit a bit more of an understanding for it.
"We've had priorities over the summer and we've ticked a fair few of them off in every position, our first-choice targets in every position really. We have to wait for the first choice in some of the other positions. We'll just have to see how that develops."
It comes after Swansea were held to a 1-1 draw in their friendly clash with Plymouth in Devon. Joel Piroe's stunning first-half volley looked to have won it for the visitors, although Ryan Hardie coolly beat Andy Fisher at the death.
"I think it was really good for us," said the head coach on his side's performance. "I really liked loads of the first-half.
"We got a bit sloppy after we scored but then we regained control. We gave them three shots on target and conceded one at the end which is frustrating. But we had a lot of changes by that point, a lot of young men getting a taste of first-team football, a number of new signings who are getting used to what we're doing and a couple of guys getting used to new positions.
"So on the whole, really good. There's loads to improve on, but loads of good stuff to show in evidence to the boys that their work is paying off, and physically it's loads more minutes in the tank for players so it's good."
Swansea face Bristol Rovers behind-closed-doors on Saturday before concluding their summer schedule against Charlton Athletic at The Valley on July 23 - a week before their Championship opener at Rotherham United.
