Northampton Saints' interim director of rugby Alan Gaffney appeared to suggest George North did not want to play in the 34-25 defeat to Sale on Saturday.
North is part of Wales' squad but was available to play for the Saints as there were no matches in the Six Nations this weekend.
But the 25-year-old was not included in Saints' squad, and Gaffney said: "I'm just disappointed he wasn't here."
When asked whether North did not want to play, Gaffney said: "That's a very difficult question to answer for me.
"I haven't spoken to George personally. In one sense it's probably best to ask George.
"We picked a side that actually wanted to be out on the pitch and picked the best side for the game for Northampton."
North joined Northampton in 2013 from Scarlets, but is returning to Wales at the end of the season after signing a National Dual Contract with the WRU.
