Mick Beale says he has not made a final decision on whether Conor Masterson will be loaned out again by QPR.
The Irishman, who turns 24 in September, has had loan spells at Swindon, Cambridge United and Gillingham.
He is behind Rob Dickie, Jimmy Dunne and recent signing Jake Clarke-Salter in the pecking order of centre-backs.
That is partly why Masterson has featured in midfield during pre-season.
He previously played in that position at Liverpool, where new R’s head coach Beale worked with him.
Now Beale must decide whether to keep Masterson in his squad as a back-up option or arrange another loan move.
“There’s no decision been made on that yet,” Beale said.
“We’ve got what I would call three ‘senior’ centre-backs and then we’ve got Conor and Joe Gubbins and I’ve been looking at both of them.
“I had Conor in the Under-14s, Under-15s and then in the 23s, so I know him very well.
“When I was at Liverpool he was a midfielder and now I’ve come here and he’s making his trade as a centre-half.
“I’m keen to look at him in both positions and he has attributes to play in both.”
Meanwhile, Beale expects Chris Willock, Luke Amos and Tyler Roberts to all be available for Saturday’s Championship opener against Blackburn.
