The Republic of Ireland international's deal at The Hawthorns runs out at the end of the season, with a further year in the club's favour.
Long came close to joining Hull in the summer, and the likes of Stoke and Newcastle, along with the Tigers, have been linked with a move for him in January.
Long's position has been strengthened by his two goals in Monday's derby against Aston Villa, and manager Steve Clarke expressed his confidence that the club "will sit down sometime in the future and sort his contract out".
Long said in the Birmingham Mail: "The manager has always been good to me.
"He reassured me I was always a big part of his plans and I get on really well with the lads here as well.
"I am settled in Birmingham so I'm enjoying my time at West Brom and hopefully the rest will take care of itself.
"There are no developments yet but there is plenty of time left on my contract and I'm sure the club will think about what's best for them and me and we'll see what happens."
