Erat, 32, requested to be traded at the beginning of the season, but word didn't start to leak out until Nov. 24.
The following day, the Capitals acknowledged the news and GM George McPhee indicated that he had been trying to find Erat a new home.
Several teams have inquired about Erat, but the asking price is believed to be a little high.
The Capitals gave up top prospect Filip Forsberg for Erat and Michael Latta on Apr. 3, 2013, and it's believed McPhee is asking for a good prospect in exchange for Erat.
The other stumbling block is Erat's contract. While he's earning $3.75 million this season and set to earn $2.25 million next season, Erat's salary cap hit is still $4.75 million, which poses a problem for a number of clubs.
Erat also has a no-movement clause and would have to approve any deal the Capitals make, though he's already submitted a list of teams he would accept a trade to.
In 27 games with the Capitals so far this season, Erat has recorded just nine assists playing very limited ice time.
