Taylor was making his first Premier League start since March 2012 for Newcastle but could not last until half-time, suffering another knee injury which fans will hope is not a long-term one.
Boss Alan Pardew confirmed after the game that Taylor will be sent off for an immediate scan.
And Barton took to Twitter to wish his former team-mate all the best, admitting that, if anyone deserves some luck, it is Taylor.
The game itself was won 1-0 by the Magpies after a fine team goal was converted by Moussa Sissoko in the second half. The victory is Newcastle's fifth league win in a row and Pardew's side are, incredibly, now fourth in the table.
Barton, however, feels it was an even game after QPR gave a very good account of themselves. He also thanked fans for their reception - the 32-year-old spent four years at St James' Park before moving to the R's.
Gutted with the result. Felt it was a very even game. Great to be back at SJP and thanks for the reception, it meant a lot.— Joseph Barton (@Joey7Barton) November 22, 2014
Also big shout to all QPR a fans who travelled up from West London. Sorry we couldn't send you back on that long journey happier.— Joseph Barton (@Joey7Barton) November 22, 2014
