According to the New York Times, Major League Baseball’s players union told agents in an e-mail message that the trading card company Upper Deck was experiencing financial difficulty and had not paid a large number of players money it owed them.
The union said it was working with Upper Deck to ensure that the players would be paid. The union strongly advised players not to return to Upper Deck any autographs they had signed for the company or to enter into any new agreements with the company until the payments were made.
The e-mail message was from Evan Kaplan, the union’s director for trading cards and collectibles, and was sent to all player agents. A person who received the e-mail provided a copy of it to The New York Times on the condition that the person not be identified.
A spokesman for the union declined to comment. A spokesman for Upper Deck did not respond to an e-mail message.
About a month ago, Upper Deck settled a lawsuit by agreeing to pay Major League Baseball Properties a “substantial” but undisclosed amount for issuing three sets of cards since last year without a license. It also agreed to pay baseball $2.4 million to settle previous debts.
In the lawsuit filed in January, M.L.B. Properties accused Upper Deck of trademark infringement and asked that it be restrained from using teams’ uniforms, helmets and cap logos.
Last summer, baseball chose Topps as its exclusive licensee, leaving Upper Deck without a license for the first time since 1989.
